Description

Optical lens system for microscope

The present invention relates to an optical lens system for a microscope, and more specifically, under <a simple structure in which a lens and a pinhole aperture are simply combined>, rather than the conventional complex structure in which a plurality of objective lenses and alternative lenses are linked. In addition, the present invention relates to an optical lens system for a microscope that can adjust and provide a high quality sample magnification image having good optical aberration at various various magnifications.

In general, the microscope module is widely known as a very useful device for enlarging and outputting a sample so small that it cannot be seen by the naked eye, and inducing a user to effectively observe the sample. Such a conventional microscope module (e.g., a compound optical microscope module) has traditionally been equipped with a series of optical lens systems in which a plurality of objective lenses and alternative lenses are linked and combined, and thus, <focus by objective lenses>. Through a complex structure that magnifies the image of the fitted sample with alternative lenses, a series of sample enlargement functions are performed.

As such, the optical lens system provided in the conventional microscope module has a series of sample enlargement functions through a complex structure that enlarges an image of a sample focused by a plurality of objective lenses to alternative lenses. The reason for this is that such a complicated structure can provide an advantageous effect in its own way in adjusting and providing a high quality image at various various magnifications.

Of course, in this situation, unless a separate action is taken, the conventional optical lens system is more than necessary due to the combined use of a plurality of objective lenses and alternative lenses, the length, occupied space, etc. Inevitably, the inevitable disadvantage of becoming larger is inevitably presented, and under such a background, the conventional microscope module is inevitably very unsuitable for use for the purpose of easily observing a target sample at any time while carrying a user.

Recently, consumer demand for improving the functions of various electronic devices such as mobile communication terminals, digital cameras, game machines, digital multimedia broadcasting (DMB) receivers, content players (eg, audio / video players, etc.) While widespread, efforts are being made to add additional new functions to these electronics, such as microscope functions.

However, as described above, the conventional optical lens system for microscopes has its own overall length (occupied space) because it links and uses a plurality of objective lenses and alternative lenses to provide high quality images at various magnifications. ) Inevitably becomes larger than necessary, and in the aftermath, it provides little space for additional circuit modules for connecting external devices. In the end, each of the electronic devices described above will have a lot of difficulties in the concrete realization of the above-described electronic devices, for example, despite the urgent need for new additional functions of the microscope function. The problem of not being able to be adopted becomes more serious as the size of electronic equipment becomes smaller. ).

Accordingly, it is an object of the present invention to pinpoint apertures that reduce the width of light incident from the target sample side through self-equipped pinholes, and to the front or rear of the pinhole aperture (or both front and rear). The lens group that reduces the optical aberration of the sample magnified image by preventing the light beam passing through the pinhole aperture from being selectively disposed in the lens group (Note: in the present invention, the term <lens group> includes the case where only one lens is used. In addition, the magnification of the sample enlarged image is continuously controlled by adjusting the distance between the pinhole diaphragm and the lens group so as to allow the same movement as necessary, and adjusting the distance between them and the target sample as necessary. In this way, the lens system for the microscope is not a conventional complex structure in which a plurality of objective lenses and alternative lenses are linked, but the lens group and the pinhole aperture are shortened. Even under the extremely simple structure of the combination, the size of the microscope lens system (length of total length) can be adjusted and provided with various magnifications of high quality (that is, well corrected optical aberration). ) It naturally induces the reduction of the probability of the arrangement of the circuit module for connecting to external devices and as a result, the lens system acts as a sample enlargement device to newly improve the function of the electronic device through linkage with other electronic devices. To induce flexibility.

Other objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

In order to achieve the above object, in the present invention, a pinhole aperture for reducing the width of the light incident to the image sensing unit side from the target sample side through a pinhole (self-equipped); Disclosed is an optical lens system for microscopy including a lens group disposed on the front or rear of the pinhole stop and preventing optical rays from passing through the pinhole so as to reduce optical aberration of an enlarged sample image formed on the image sensing unit. do.

In another aspect of the present invention, a pinhole aperture for reducing the width of light incident from the target sample side to the image sensing unit through a pinhole provided therein; A lens group disposed at the front or the rear of the pinhole stop and preventing optical rays from passing through the pinhole so as to reduce optical aberration of the magnified image formed in the image sensing unit; Disclosed is an optical lens system for a microscope, comprising a camera lens group disposed on a rear surface of the lens group (ie, an image sensing unit side) and forming the sample magnified image on the image sensing unit.

In the present invention, a pinhole aperture that reduces the width of light incident from the target sample side through a self-equipped pinhole, and selectively disposed in front or behind (or both front and rear) of the pinhole aperture. In this state, the light beams passing through the pinhole aperture are not spread, and the lens group which reduces the optical aberration of the sample enlarged image is linked and arranged, and the pinhole aperture and the lens group can be moved as needed. In the fixed state, since the magnification of the sample magnification image is continuously adjusted by adjusting the distance between them and the target sample, under the implementation environment of the present invention, in the lens system for a microscope, the <multiple objective lenses and alternatives High quality (i.e. optical) under &lt; an extremely simple structure with a simple combination of lens groups and pinhole apertures &gt; It is possible to adjust and provide a sample amplification image of well-corrected aberration with various various magnifications, and finally, it becomes possible to naturally realize the reduction of its size and the expansion probability of the arrangement of the circuit module for connecting external devices. As a result, through linkage with other electronic devices, it is possible to flexibly perform the role of the sample expanding device to newly improve the function of the electronic device.

Hereinafter, with reference to the accompanying drawings, the optical lens system for a microscope according to the present invention in more detail as follows.

As shown in FIG. 1, the optical lens system 10 for a microscope according to the present invention includes a lens group 11 installed in an electronic device including a light source (not shown), an optical / electric conversion processing board 101, and the like. , The pinhole stop 13, the optical filter 12, and the like are closely combined.

At this time, while the light source (for example, LED) is electrically connected to the power source of the electronic device such as a battery, when the power supply side power is supplied, a series of light rays are supplied to the target sample side, the light beam from the target sample (not shown) side The light / electric conversion processing board 101 is to guide the output, the light incident from the target sample side through the lens group 11, the pinhole aperture 13, the optical filter 12, When inputted in the state of containing the enlarged sample image, by using the self-equipped image sensing unit 102 to form the image enlarged image, and to perform the process of converting the image enlarged sample enlarged image to an electrical signal do.

In this case, the image sensing unit 102 included in the photoelectric conversion board 101 may generate and accumulate by photodiodes and photodiodes that receive light rays, for example, to generate and accumulate a series of optical charges. Signal processing transistors for carrying / discharging the photocharges to necessary elements in an electronic device, a circuit set for correcting and converting an electrical signal, etc., will be stably equipped.

At this time, the optical filter 12 of the present invention has a structure disposed between the pinhole aperture 13 and the image sensing unit 102, and some of the rays passing through the pinhole aperture 13, for example, It plays a role of stably blocking unnecessary rays (such as infrared rays) except for visible rays.

Here, as shown in the figure, the pinhole stop 13 of the present invention is provided with a pinhole 13a of a fine needle hole type. Of course, in such a situation in which the pinhole 13a is provided, the light incident from the target sample side can be greatly reduced in width by the diameter of the pinhole 13a.

At this time, in the present invention, the pinhole 13a of the pinhole stop 13 described above is preferably induced to have a diameter in the range as shown in Equation 1 below.

Where D is the diameter of the pinhole

At this time, if the pinhole 13a of the pinhole aperture 13 has a diameter smaller than the above lower limit value (that is, 0.04 mm), not only the diffraction effect of the light beam passing through the pinhole 13a becomes too large, but also modulation The problem that the value of the MTF (Modulation Transfer Function) decreases may be caused.

On the other hand, when the pinhole 13a of the pinhole aperture 13 has a diameter larger than the above upper limit value (ie, 1.1 mm), the diffraction limit curve of the modulation transfer function value is provided, but in this case, the optical aberration is increased. May cause another problem, and furthermore, the overall length of the lens system 10 may be increased, which may cause another problem that is contrary to the miniaturization of electronic devices.

On the other hand, in the above-described arrangement of the pinhole stop 13, the light ray passing through the pinhole 13a is due to its own intrinsic properties (or the influence of the pinhole) such as the straightness of the light, for example, the pinhole 13a. As soon as it passes, it causes a wide spread problem.

In such a situation, in the present invention, as shown in the drawing, the front surface of the pinhole stop 13 has a predetermined amount of total refractive power, which is incident from the target sample side to the pinhole stop 13 side. The degree of refraction (for example, the angle of refraction) of the light beams is adjusted in advance, and through this, a measure of additionally arranging one lens group 11 for inducing the light beams passing through the pinhole 13a to not spread is taken.

In this case, the lens group 11 of the present invention is preferably provided with at least one aspherical surface 11a in order to improve the quality of the sample magnified image formed on the image sensing unit 102 side.

Of course, in such an arrangement of the lens group 11, when the degree of refraction (eg, angle of refraction) of the light beam is adjusted within a predetermined range, it is incident from the target sample side to the pinhole aperture 13 side and passes through the pinhole 13a. The rays of light may be reduced in spite of their own intrinsic properties or the pinholes 13a, and thus, the magnified image that is finally imaged on the image sensing unit 102 may have various optical aberrations, for example. For example, spherical aberration, astigmatism, distortion aberration, and the like can be well corrected.

At this time, in the present invention, the above-described lens group 11 is preferably induced to have a total refractive power in the range as shown in Equation 2 below.

(P is the total refractive power of the lens group 11, L is the distance between the target sample and the first refractive surface 11a of the lens group 11, T is the first of the lens group 11) Distance from the refracting surface 11a to the last refracting surface 11b) (in this case, the total refractive power P of the lens group is calculated based on the helium d-line (587.56 mm))

보다 적은 총 굴절능 을 가지게 되면, 광선의 굴절각도가 필요이상으로 완만해져, 렌즈군(11)의 배치에도 불구하고, 광선이 핀홀(13a)을 통과하는 즉시, 퍼지는 문제점이 야기되거나, 시료확대 이미지를 결상하기 위한 초점길이가 너무 길어져, 렌즈군(11) 및 이미지 센싱유닛(102) 사이의 거리 역시 너무 멀어지게 되고, 그에 따라, 렌즈 시스템(10)의 전장길이 역시 길어지게 됨으로써, 결국, 전자기기의 초소형 화에 반하게 되는 또 다른 문제점이 야기될 수 있게 된다.At this time, if the lens group 11 described above,

If the total refractive power is smaller, the angle of refraction of the light beam becomes more than necessary, and despite the arrangement of the lens group 11, the light beam passes through the pinhole 13a, causing the problem of spreading or expanding the sample. The focal length for forming an image becomes too long, so that the distance between the lens group 11 and the image sensing unit 102 becomes too far, and accordingly, the overall length of the lens system 10 also becomes long, so that eventually, Another problem may arise that is contrary to the miniaturization of electronic devices.

보다 큰 총 굴절능을 가지게 되면, 광선의 굴절각도가 필요이상으로 경사져, 최종 결상되는 시료확대 이미지가 너무 적어지고, 그 결과, 이미지 센서유닛(102)의 픽셀을 효율적으로 모두 사용하지 못하게 되는 문제점이 야기될 수 있으며, 나아가, 시료확대 이미지를 결상하기 위한 초점길이가 너무 짧아져, 렌즈군(11) 및 이미지 센서유닛(102) 사이의 거리 역시 너무 짧아지게 되고, 그에 따라, 렌즈 시스템(10)의 전장길이 역시 너무 짧아지게 됨으로써, 결국, 상술한 광학필터(12)를 정상적으로 설치하지 못하게 되는 또 다른 문제점이 야기될 수 있게 된다. On the other hand, the lens group 11 described above is the upper limit value, that is,

If the total refractive power is greater, the angle of refraction of the light beam is inclined more than necessary, resulting in too small a sample enlarged image to be finally formed, and as a result, the pixels of the image sensor unit 102 cannot be used efficiently. This can be caused, and furthermore, the focal length for forming the specimen magnification image becomes too short, so that the distance between the lens group 11 and the image sensor unit 102 becomes too short, and accordingly, the lens system 10 Also, the overall length of a) becomes too short, which may result in another problem of failing to install the above-described optical filter 12 normally.

On the other hand, since the optical lens system 10 for a microscope of the present invention performs a series of microscope functions in a state in which it is installed in an electronic device, under the implementation environment of the present invention, the image sensing unit 102 is finally imaged. The sample magnification image needs to be provided at various magnifications, depending on the intention of the user of the electronic device.

Under this necessity, in the present invention, the pinhole aperture 13 / lens group 11 assembly is connected to the specimen enlarged image while the pinhole aperture 13 and the lens group 11 are integrally fixed to allow the same movement. Whenever magnification adjustment is needed, measures are taken to guide the movement away from or close to the target sample.

In this case, of course, in the electronic device, while forming a mechanical / electrical connection relationship with the pinhole stop 13 / lens group 11 assembly, the pinhole stop 13 / lens group ( 11) Various lens driving devices (e.g. motors, shafts, gears, etc.) that can guide the assembly to move back and forth are additionally arranged (the types, arrangements, etc. of such lens driving devices may be Various variations can be achieved).

Under this measure, the user manipulates the electronic device, and accordingly, various lens driving devices such as a motor, a shaft, a gear, and the like take action, so that the pinhole aperture 13 / lens group 11 assembly of the present invention is subjected to a target sample. When it becomes possible to continuously take an operation away from or close to the distance, the distance from the pinhole aperture 13 / lens group 11 assembly to the image sensing unit 102 is continuously changed in accordance with the above operation. As a result, the sample magnified image that is finally formed in the image sensing unit 102 may also be continuously enlarged or reduced.

Naturally, in the implementation environment of the present invention, the user side using the electronic device operates the electronic device to adjust the distance between the target sample and the pinhole aperture 13 / lens group 11 assembly closer or farther. With only a very simple measure, the magnification of the sample magnified image finally formed in the image sensing unit 102 can be adjusted freely (of course, if such a step is omitted as necessary, the optical lens system for a microscope of the present invention). Can effectively provide a fixed magnification image with well corrected optical aberrations).

That is, in this invention, in the state selectively arrange | positioned in front of the pinhole stop 13 and the pinhole stop 13 which reduce the width | variety of the light which injects from the target sample side via the pinhole 13a provided in itself, In addition to linking and arranging the lens group 11 which reduces the optical aberration of the sample enlarged image by preventing the light beam passing through the pinhole aperture 13 from spreading, the pinhole aperture 13 and the lens group ( 11) in the fixed state to enable the same movement, by adjusting the distance between these assemblies and the target sample, the magnification of the sample magnification image is induced to be controlled continuously, under the implementation environment of the present invention, under the microscope On the lens system 10 side, under <a simple structure in which the lens 11 and the pinhole aperture 13 are simply combined>, not <the conventional complex structure in which a plurality of objective lenses and alternative lenses are linked> In addition, it is possible to adjust and provide high-quality clear sample magnification images at various magnifications (of course, if necessary, fixed magnifications), thereby reducing the size of the device and increasing the probability of arrangement of circuit modules for connecting external devices. Can be realized naturally, and as a result, by linking with other electronic devices, it is possible to flexibly play the role of a sample enlargement device to newly improve the function of the electronic device.

On the other hand, under the system of the present invention, if the user carries the electronic device and needs to observe the target sample, the electronic device approaches the target sample, and the microscope optical lens system 10 Induce access, then manipulate the power supply (e.g., operate the power supply switch) so that power on the power source side is supplied to the light source side, thereby taking action to induce the light source to irradiate the light beam onto the target sample side. do.

Of course, in this situation, due to the light source side light irradiation, the light rays output from the target sample side are refracted by the refracting surface 11a, the aspherical surface of the lens group 11, the refracting surface 11b and the like convex toward the pinhole stop 13 side. After passing through, through the pinhole 13a of the pinhole aperture 13, through each surface 12a, 12b of the optical filter 12, and then reaching the pixel of the image sensing unit 102, a series of As a result, an image of a magnified sample image is subjected to a procedure. As a result, the user side can flexibly enjoy the effect of easily magnifying and observing a desired target sample at any time, unlike in the prior art.

Specific implementation data of the optical lens system 10 for a microscope according to the present invention described above is given by the following Tables 1 and 2 (wherein the material forming the lens group 11 is manufactured by Zeon, Japan). ZEONEX Z-E48R is optionally used) (Table 2 below shows the aspherical surface constant of the refracting surface 11a, which is an aspherical surface of the lens group 11, and in these Table 2, E + 01, E-01 and the like are respectively 10 ⁺¹ , 10 ^-1, etc., the same below).

At this time, the aspherical surface 11a (Aspheric surface) included in the lens group 11 is expressed by the following formula (3) (the same aspherical formula is the same in all the following data).

Where Z is the depth in the axial direction from the tangent plane that meets the vertex of the aspherical surface, c ₀ is the curvature of the aspheric surface near the beam axis, h is the height from the beam axis, and K is Conic Constant, A is a fourth order aspheric constant, B is a sixth order aspheric constant, C is an eighth order aspheric constant, D is a tenth order aspheric constant, E is a 12th order aspheric constant, F is a 14th order aspheric constant, G Is the 16th order aspheric constant, H is the 18th order aspheric constant, J is the 20th order aspheric constant)

Here, the pinhole 13a of the pinhole aperture 13 has a diameter D of 0.2 mm, as shown in Table 1, thereby satisfying the conditions shown in Equation 1 above, and the lens group 11 ) Has a total refractive power P of 0.442 mm ⁻¹ while having a distance T from the first refractive surface 11a to the last refractive surface 11b to 1.0525 mm from the data presented in Table 1 above. It satisfies the conditions given in Equation 2 below.

Under the data given in Table 1 and Table 2, as shown in FIG. 2, the sample magnification image finally formed in the image sensing unit 102 is C-line (656.3 nm), d-line ( 58 spherical aberration within the range of about 0.1 mm is shown over a wavelength of light such as 587.6 nm), e-line (546.1 nm), F-line (486.1 nm), g-line (435.8 nm), and the like.

In addition, the sample magnified image finally formed in the image sensing unit 102, as shown in Figure 2, in the sagittal (S), Tangential (Tangential) T, astigmatism within the range of about 0.1 mm It is shown.

In addition, the sample magnification image finally formed in the image sensing unit 102, as shown in Figure 2, exhibits a distortion of about 3.5% of the maximum size.

As such, in the implementation environment of the present invention, as shown in FIG. 2, the sample magnification image finally formed in the image sensing unit 102 can be seen that the optical aberration is generally well corrected.

On the other hand, under the data given in Tables 1 and 2 above, the optical lens system 10 for a microscope according to the present invention is connected to and installed in an electronic device, and then the wavelength of 435.8 nm to 656.3 nm toward the target sample. While irradiating light rays having an area, the lens group 11 / pinhole stop 13 assembly is moved to adjust the distance L between the target sample and the first refractive surface 21a of the lens group 21 to 5.5 mm to 12.0 mm. In this case, of course, in this case, it can be seen that the lens group 11 satisfies the limitation condition shown in Equation 2 above, and as shown in Table 3 below, the last refractive surface of the lens group 11 It can be seen that the distance from the image sensing unit 102 to the image sensing unit 102 continuously undergoes a change that becomes longer or shorter in accordance with the above-described operation, and thus, the sample magnified image finally formed in the image sensing unit 102. Again, the change is expanded or reduced from 1 to 7.2 times. It can be seen that it occurs rapidly.

On the other hand, as shown in Figure 3, under another embodiment of the present invention, the optical lens system 20 for a microscope, unlike the previous embodiment, the lens group 21 to the rear of the pinhole aperture 23 1 Each structure is arranged (wherein the detailed description of the pinhole stop 23 having the pinhole 23a, the detailed description of the optical filter 22 having the facets 22a, 22b, etc. are mentioned above). To one statement).

Of course, also in this case, the pinhole stop 23 and the lens group 21, if necessary, forms a structure that is fixed integrally to enable the same movement, in this situation, the lens group 21 is By maintaining the total refractive power within a certain range, it adjusts the degree of refraction (eg, the angle of refraction) of the light beams passing through the pinhole 23a of the pinhole aperture 23, thereby adjusting the light ray does not spread. (In this case, the lens group 21 of the present invention is preferably provided with at least one aspherical surface 21a, 21b to improve the quality of the sample magnified image which is finally formed on the image sensing unit 102 side. do).

In the arrangement of the lens group 21, when the degree of refraction (eg, angle of refraction) of the light beam is adjusted within a predetermined range, the light beam passing through the pinhole 23a has its own unique property, or of the pinhole 23a. In spite of the influence, the spreading width can be reduced, and thus, the magnified image which is finally formed in the image sensing unit 102 can have various optical aberrations such as spherical aberration, astigmatism, Distortion aberration or the like can be corrected well.

In this case, in the present invention, in consideration of the occurrence of the above-described various problems, the total refractive power of the lens group 21 is maintained in the range shown in Equation 2 above, through which the pinhole 23a is passed. By normally suppressing the spreading of light rays, the sample magnified image finally formed in the image sensing unit 102 is induced to have good optical aberration.

On the other hand, in another embodiment of the present invention, when the magnification adjustment of the sample magnification image is necessary, the user operates the various electronic devices, such as motors, shafts, gears to operate the lens driving inducing devices, the aftermath As such, the lens group 21 / pinhole stop 23 assembly of the present invention, which is integrally fixed to enable the same movement, can continuously move away from or close to the target sample.

Of course, even in this situation, the distance from the lens group 21 / pinhole aperture 23 assembly to the image sensing unit 102 can continuously undergo a longer or shorter change in accordance with the above-described operation. The sample magnified image that is finally formed in the image sensing unit 102 may also continuously change the enlarged or reduced image.

As a matter of course, even under such a different implementation environment of the present invention, the user side using the electronic device operates the electronic device to close or move the distance between the target sample and the lens group 21 / pinhole aperture 23 assembly. With only a very simple measure to adjust, the magnification of the sample magnified image finally formed in the image sensing unit 102 can be freely adjusted (in this case, if the above measures are omitted as necessary, for the microscope of the present invention). The optical lens system 20 can effectively provide a fixed magnification image of which optical aberration is well corrected).

On the other hand, under such a different system of the present invention, if the user carries the electronic device and needs to observe the target sample, the electronic device approaches the target sample, and the microscope optical lens system 20 is connected to the target sample. Induce access, then manipulate the power supply (e.g., operate the power supply switch) so that power on the power source side is supplied to the light source side, thereby taking action to induce the light source to irradiate the light beam onto the target sample side. do.

Of course, in this situation, due to the light source side light irradiation, the light beam output from the target sample side passes through the pinhole 23a of the pinhole aperture 23, and the refractive surface 21a and the refractive surface (which are aspherical surfaces of the lens group 21). 21b) and the like, and then pass through the surfaces 22a and 22b of the optical filter 22, and then reach the pixels of the image sensing unit 102 to be formed into a series of enlarged sample images. In the end, as in the previous embodiment, the user side can flexibly enjoy the effect of easily magnifying and observing a target sample anytime and anytime.

Here, the pinhole 23a of the pinhole aperture 23 has a diameter D of 0.2 mm, as shown in Table 4, thereby satisfying the conditions shown in Equation 1 above, and the lens group 21 ) Has a total refractive power P of 0.427 mm ⁻¹ , while having a distance T from the first refractive surface 21 a to the last refractive surface 21 b of 0.5136 mm from the data shown in Table 4 above.

While irradiating light rays having an area, the lens group 21 / pinhole stop 23 assembly is moved to adjust the distance L between the target sample and the first refractive surface 21a of the lens group 21 to 5.6 mm to 12.1 mm. In this case, of course, in this case, the lens group 21 satisfies the limitation condition shown in Equation 2 above, and as shown in Table 7, the last refractive surface of the lens group 21. It can be seen that the distance from the image sensing unit 102 to the image sensing unit 102 continuously undergoes a change that becomes longer or shorter according to the above-described operation, and thus, the sample enlarged image finally formed in the image sensing unit 102. Again, the change is magnified or reduced by 1 ~ 8.9 times It can be seen that continuously produces a.

On the other hand, as shown in Figure 5, under another embodiment of the present invention, in the optical lens system 30 for a microscope, unlike the previous embodiment, the lens group (31, 34) of the pinhole aperture 33 The structure is arranged in pairs on the front surface and is arranged in two pieces (herein, a detailed description of the pinhole diaphragm 33 having the pinhole 33a, the optical filter 32 having the respective surfaces 32a and 32b). The detailed description thereof will be replaced with the above-described details (in this case, as shown in the drawing, the lens groups 31 and 34 may be combined in a single unit form (Cemented), depending on the situation. They may be separated by a distance).

Of course, even in this case, the pinhole stop 33 and the lens groups 31 and 34 form a structure in which the pinhole aperture 33 and the lens groups 31 and 34 are integrally fixed to allow the same movement as necessary. ) Adjusts the degree of refraction (eg, angle of refraction) of the light beams passing through the pinholes 33a of the pinhole aperture 33 by keeping its total refractive power within a certain range, thereby adjusting the light rays from spreading. (In this case, the lens groups 31 and 34 of the present invention are preferably one or more aspherical surfaces 31a in order to improve the quality of the sample magnified image finally formed on the image sensing unit 102 side. )).

Of course, in the arrangement of the lens groups 31 and 34, when the degree of refraction (eg, angle of refraction) of the light beam is adjusted within a certain range, the light beam passing through the pinhole 33a has its own unique property or pinhole. Despite the influence of (33a), it is possible to reduce the spreading width, and eventually, the sample magnified image finally formed in the image sensing unit 102 is a variety of optical aberration, for example, spherical aberration, astigmatism Astigmatism, distortion aberration, etc. can be corrected well.

Even in this case, in the present invention, the total refractive power of the lens groups 31 and 34 is maintained in the range shown in Equation 2 in consideration of the occurrence of various problems described above, and thus, the pinhole 33a is provided. By normally suppressing the propagation of light rays passing through, the magnified image that is finally formed in the image sensing unit 102 is induced to have good optical aberration.

As a result, the enlarged or shortened change may be continuously experienced, and thus, the magnified image that is finally formed in the image sensing unit 102 may also be continuously enlarged or reduced.

As a matter of course, even under such an implementation environment of the present invention, the user side using the electronic device operates the electronic device to close the distance between the target sample and the lens group 31, 34 / pinhole stop 33 assembly. With only an extremely simple measure of adjusting the distance or distance, the magnification of the sample magnification image finally formed in the image sensing unit 102 can be freely adjusted continuously (in this case, if the above measures are omitted as necessary, the present invention). The optical lens system 30 for microscopy can effectively provide a fixed magnification image with good optical aberration corrected).

On the other hand, under another system of the present invention, if the user carries the electronic device and needs to observe the target sample, the electronic device approaches the target sample, and the optical lens system 30 for a microscope provides the target sample. Induces access to and then manipulates the power supply (e.g., operates a power supply switch) so that power on the power source side is supplied to the light source side, thereby taking action to induce the light source to irradiate the light beam onto the target sample side. Done.

In this situation, of course, due to the light source side light irradiation, the light rays output from the target sample side are convex toward the refractive surface 31a and the refractive surface 31b, which are aspherical surfaces of the lens groups 31 and 34, and the optical filter 32 side. After passing through the refractive surface 34a and the like of the lens group 31 and 34, and then through the pinhole 33a of the pinhole aperture 33, it passes through each surface 32a and 22b of the optical filter 32, The pixel of the image sensing unit 102 is reached and undergoes a process of forming an image into a series of <enlarged sample images>. Consequently, as in each of the foregoing embodiments, the user may select a target sample that he / she wants at any time and any time. Flexibility to enjoy the effects that can be easily magnified.

In addition, the sample magnification image finally formed in the image sensing unit 102, as shown in Figure 6, exhibits a distortion of a maximum size of about 2.98%.

As such, under the implementation environment of the present invention, as shown in FIG. 6, the sample magnification image finally formed in the image sensing unit 102 can be seen that the optical aberration is generally well corrected.

On the other hand, under the data given in Tables 8 and 9, after connecting and installing the optical lens system 30 for a microscope according to the present invention to an electronic device, a wavelength of 435.8 nm to 656.3 nm toward the target sample. While irradiating a light beam having an area, the lens group 31, 34 / pinhole stop 33 assembly is moved so that the distance L between the target sample and the first refractive surface 31a of the lens group 31, 34 is 5.0 mm to When adjusted to 12.0 mm (of course, in this case, it can be seen that the lens group 31, 34 satisfies the constraint set forth in the equation (2)), as shown in Table 10 below, lens group The distance from the last refracting surface 34a of (31, 34) to the image sensing unit (102) is consistent with the movement of the above-mentioned pinhole aperture (33) / lens group (31, 34) assembly, continuously changing the lengthening or shortening change.

(At this time, the lens groups 41 and 44 may be separated with a distance, as shown in the drawing. May be combined into a single unit).

Of course, even in this case, the pinhole stop 43 and the lens groups 41 and 44 form a structure in which the pinhole diaphragm 43 and the lens groups 41 and 44 are integrally fixed to allow the same movement as necessary. ) Adjusts the degree of refraction (eg, angle of refraction) of the light beams passing through the pinhole 43a of the pinhole aperture 43 by maintaining its total refractive power within a predetermined range, and thereby, prevents the light beam from spreading. (In this case, the lens groups 41 and 44 of the present invention are preferably one or more aspherical surfaces 41b to improve the quality of the sample magnified image finally formed on the image sensing unit 102 side. ) And an aspherical surface 44a).

Of course, in the arrangement of the lens groups 41 and 44, when the degree of refraction (eg, angle of refraction) of the light beam is adjusted within a predetermined range, the light beam passing through the pinhole 43a has its own unique property or pinhole.

Astigmatism, distortion aberration, etc. can be corrected well.

In this case, in the present invention, the total refractive power of the lens groups 41 and 44 is maintained in the range shown in Equation 2 in consideration of the occurrence of the various problems described above, and thus, the pinhole 43a By normally suppressing the propagation of light rays passing through, the magnified image that is finally formed in the image sensing unit 102 is induced to have good optical aberration.

On the other hand, in another embodiment of the present invention, when it is necessary to adjust the magnification of the sample magnification image, the user operates the various electronic devices, such as a motor, a shaft, a gear, driving the lens driving inducing devices, In the aftermath, the lens group 41,44 / pinhole stop 43 assembly of the present invention, which is integrally fixed to enable the same movement, can continuously move away from or close to the target sample.

As a result, the enlarged or shortened change may be continuously experienced, and thus, the magnified image that is finally formed in the image sensing unit 102 may also be continuously enlarged or reduced.

Naturally, even under such an implementation environment of the present invention, the user side using the electronic device operates the electronic device to close the gap between the target sample and the lens group 41, 44 / pinhole stop 43 assembly. With only an extremely simple measure of adjusting the distance or distance, the magnification of the sample magnification image finally formed in the image sensing unit 102 can be freely adjusted continuously (in this case, if the above measures are omitted as necessary, the present invention). The optical lens system 40 for microscopy can effectively provide a fixed magnification image with good optical aberration corrected).

On the other hand, under another system of the present invention, if the user carries the electronic device and needs to observe the target sample, the electronic device approaches the target sample, and the microscope optical lens system 40 provides the target sample. Induces access to and then manipulates the power supply (e.g., operates a power supply switch) so that power on the power source side is supplied to the light source side, thereby taking action to induce the light source to irradiate the light beam onto the target sample side. Done. Of course, in this situation, due to the light source side light irradiation, the light beam outputted from the target sample side passes through the pinhole 43a of the pinhole aperture 43 and is refracted by the convex surface 41a of the pinhole aperture side of the lens groups 41 and 44. ), The refracting surface 41b of the aspherical lens groups 41 and 44 and the refracting surface 44a, and further, the optical fiber 42 passes through the refracting surface 44b of the convex lens groups 41 and 44, and the like. Pass through each face 42a, 42b of the filter 42, and then reach the pixels of the image sensing unit 102, undergoing a process of forming an image into a series of <enlarged sample images>.

In the arrangement of the lens groups 51 and 54, when the degree of refraction (eg, angle of refraction) of the light beam is adjusted within a predetermined range, the light beam passing through the pinhole 53a has its own unique property, or the pinhole 53a. In spite of the influence of), the spreading width can be reduced, and thus, the magnified image that is finally formed in the image sensing unit 102 can be subjected to various optical aberrations, for example, spherical aberration and astigmatism. ), Distortion aberration and the like can be corrected well.

Here, the pinhole 53a of the pinhole aperture 53 has a diameter D of 0.3 mm, as shown in Table 14, and satisfies the conditions shown in Equation 1 above, and the lens group 51 (54) has a total refractive power P of 0.458 mm ⁻¹ while having a distance T from the first refractive surface 51 a to the last refractive surface 54 b of 1.9148 mm from the data presented in Table 14 above. , The condition given in Equation 2 above is satisfied.

Under the data given in Tables 14 and 15, as shown in FIG. 10, the sample magnification image finally formed in the image sensing unit 102 is C-line (656.3 nm), d-line ( 58 spherical aberration within the range of about 0.11 mm is shown over a wavelength of light such as 587.6 nm), e-line (546.1 nm), F-line (486.1 nm), g-line (435.8 nm), and the like.

In addition, the sample magnified image finally formed in the image sensing unit 102, as shown in Figure 10, in the sagittal S, Tangential T, astigmatism within the range of about 0.11 mm It is shown.

In addition, the sample magnification image finally formed in the image sensing unit 102, as shown in FIG. 10, exhibits distortion aberration having a maximum size of about 1.24%.

As such, in the implementation environment of the present invention, as shown in FIG. 10, the sample magnification image finally formed in the image sensing unit 102 can be seen that the optical aberration is generally well corrected.

On the other hand, under the data given in Tables 14 and 15, after connecting and installing the optical lens system 50 for a microscope according to the present invention to an electronic device, a wavelength of 435.8 nm to 656.3 nm toward the target sample. While irradiating a light beam having an area, the lens group 51, 54 / pinhole stop 53 assembly is moved, and the distance L between the target sample and the first refractive surface 51a of the lens group 51, 54 is 3.0 mm to When adjusted to 10.0 mm (of course, in this case, it can be seen that the lens group (51, 54) satisfies the constraint set forth in the equation (2)), as shown in Table 16 below, the lens group It can be seen that the distance from the last refraction surface 54b of the 51 and 54 to the image sensing unit 102 continuously undergoes a change in length or shortening according to the movement of the lens group 51 described above. In addition, the sample enlarged image that is finally imaged on the image sensing unit 102 is also magnified by 1 to 28.2 times. Or, it can be seen that causes a reduction to be changed continuously.

On the other hand, as shown in Fig. 11, under another embodiment of the present invention, the microscope optical lens system 60 of the present invention consisting of a lens group 61, a pinhole aperture 63, and the like, for example, a camera lens group (104.105) taking the structure installed in the <camera function performance type electronic device> equipped with the optical filter 103, the optical / electrical conversion processing board 101, the image sensing unit 102, and the corresponding camera function performance type It is also possible to play a role of newly granting and providing a function of a <sample enlargement device (i.e., a microscope device) to the electronic device. (Of course, under such an implementation environment of the present invention, the camera function performing electronic device is given to itself. In addition to the original camera functions, a series of microscope functions can be performed simultaneously).

In this case, the camera lens groups 104 and 105 provided in the electronic device have a structure disposed on the rear surface of the lens group 61 and the pinhole diaphragm 63 (that is, the image sensing unit side), and the lens group 61 and the pinhole. Pass the light beam through the aperture 63 to guide the image sensing unit 102 of the light / electric conversion processing board 101 to form a series of magnified images corresponding to the light beam. do.

At this time, in the optical lens system 60 for a microscope of the present invention, components such as the <pinhole diaphragm 63 and one lens group 61 positioned on the front of the pinhole diaphragm 63> include the camera lens group 104 and 105. In this situation, the pinhole aperture 63, the lens group 61, the camera lens group 104, 105, and the like are fixed and connected to each other to enable the same movement. To form a structure.

Here, the lens group 61 and the camera lens group 104 and 105 maintain their total refractive power within a predetermined range, and thus the degree of refraction of the light beam passing through the pinhole 63a of the pinhole aperture 63 (eg, the refraction angle). And, through this, it serves to adjust so that the light beam does not spread (here, the detailed description of the pinhole aperture 63 having a pinhole 63a will be replaced with the above-mentioned details).

Of course, in the arrangement of the lens group 63 and the camera lens group 103, when the degree of refraction (eg, angle of refraction) of the light beam is adjusted within a certain range, the light beam passing through the pinhole 63a is inherently unique. In spite of the property or the influence of the pinhole 63a, the spreading width can be reduced, and thus, the magnified image that is finally formed in the image sensing unit 102 can have various optical aberrations, for example, spherical aberration. Aberration, astigmatism, distortion aberration, etc. can be corrected well.

At this time, in another embodiment of the present invention, the lens group 61 and the camera lens group 104, 105 described above are preferably induced to have a total refractive power in the range as shown in Equation 4 below.

은 타겟 시료와 렌즈군(61)의 첫 번째 굴절면(61a) 사이의 거리, t는 렌즈군(61)의 첫 번째 굴절면(61a)으로부터 카메라 렌즈군(105)의 마지막 굴절면(105b)까지의 거리)(이 경우, 상기 렌즈군(61) 및 카메라 렌즈군(104,105)의 총 굴절능 p는 헬륨 d-line(587.56㎜)을 기준으로 계산함)(Where p is the total refractive power of the lens group 61 and the camera lens group 104,105,

Is the distance between the target sample and the first refractive surface 61a of the lens group 61, t is the distance from the first refractive surface 61a of the lens group 61 to the last refractive surface 105b of the camera lens group 105 (In this case, the total refractive power p of the lens group 61 and the camera lens group 104,105 is calculated based on the helium d-line (587.56 mm).)

보다 적은 총 굴절능을 가지게 되면, 광선의 굴절각도가 필요이상으로 완만해져, 렌즈군(61)의 배치에도 불구하고, 광선이 핀홀(63a)을 통과하는 즉시, 폭 넓게 퍼져 발산하는 문제점이 야기되거나, 시료확대 이미지를 결상하기 위한 초점길이가 너무 길어져, 렌즈군(61) 및 카메라 렌즈군(104,105), 그리고, 이미지 센싱유닛(102) 사이의 거리 역시 너무 멀어지게 되고, 그에 따라, 렌즈 시스템(60, 카메라 렌즈군 포함)의 전장길이 역시 길어지게 됨으로써, 결국, 전자기기의 초소형 화에 반하게 되는 또 다른 문제점이 야기될 수 있게 된다.At this time, if the lens group 61 and the camera lens group 104, 105 are the above-described lower limit value, that is,

If the total refractive power is less, the angle of refraction of the light beam becomes more than necessary, and despite the arrangement of the lens group 61, the light beam spreads and diverges as soon as it passes through the pinhole 63a. Or the focal length for forming an image enlarged image becomes too long, and the distance between the lens group 61 and the camera lens groups 104 and 105 and the image sensing unit 102 becomes too far, and thus, the lens system. The length of the overall length of the camera (including the camera lens group 60) is also increased, which may result in another problem that is contrary to the miniaturization of electronic equipment.

보다 큰 총 굴절능을 가지게 되면, 광선의 굴절각도가 필요이상으로 경사져, 최종 결상되는 시료확대 이미지가 너무 적어지고, 그 결과, 이미지 센서유닛(102)의 픽셀을 효율적으로 모두 사용하지 못하게 되는 문제점이 야기될 수 있으며, 나아가, 시료확대 이미지를 결상하기 위한 초점길이가 너무 짧아져, 렌즈군(61) 및 카메라 렌즈군(104,105), 그리고, 이미지 센서유닛(102) 사이의 거리 역시 너무 짧아지게 되고, 그에 따라, 렌즈 시스템(60, 카메라 렌즈군 포함)의 전장길이 역시 너무 짧아지게 됨으로써, 결국, 광학필터(103)를 정상적으로 설치하지 못하게 되는 또 다른 문제점이 야기될 수 있게 된다.On the other hand, the lens group 61 and the camera lens group 104 and 105 have the above upper limit values, that is,

If the total refractive power is greater, the angle of refraction of the light beam is inclined more than necessary, resulting in too small a sample enlarged image to be finally formed, and as a result, the pixels of the image sensor unit 102 cannot be used efficiently. This can be caused, and furthermore, the focal length for forming the sample enlarged image is too short, so that the distance between the lens group 61 and the camera lens group 104 and 105 and the image sensor unit 102 is too short. Thus, the overall length of the lens system 60 (including the camera lens group) is also too short, which may result in another problem of failing to install the optical filter 103 normally.

On the other hand, in another embodiment of the present invention, when it is necessary to adjust the magnification of the sample magnification image, the user operates the various electronic devices, such as a motor, a shaft, a gear, driving the lens driving inducing devices, In the aftermath, the pinhole diaphragm 63 / lens group 61 / camera lens group 104,105 assemblies, which are fixed and connected to each other to enable the same movement, can continuously move away from or close to the target sample.

Of course, even in this situation, the distance from the pinhole aperture 63 / lens group 61 / camera lens group 104,105 assembly to the image sensing unit 102 is the above-described pinhole aperture 63 / lens group 61 / camera. In accordance with the movement of the lens group 104 and 105 assembly, it is possible to continuously experience the lengthening or shortening change, and thus, the magnified image which is finally imaged on the image sensing unit 102 is also continuously enlarged or reduced. Can be caused by.

Naturally, even under such an implementation environment of the present invention, on the user side using the electronic device, the electronic device can be operated to assemble the target sample and the pinhole diaphragm 63 / lens group 61 / camera lens group 104 and 105. Even with very simple measures to adjust the distance between the two close or far, it is possible to freely continuously adjust the magnification of the magnified image that is finally formed in the image sensing unit 102 (even in this case, if necessary If omitted, the microscope optical lens system 60 of the present invention can effectively provide a magnified image of a fixed magnification with good optical aberration corrected).

On the other hand, under another system of the present invention, if the user carries the electronic device and needs to observe the target sample, the electronic device approaches the target sample, and the microscope optical lens system 60 performs the target sample. Induces access to and then manipulates the power supply (e.g., operates a power supply switch) so that power on the power source side is supplied to the light source side, thereby taking action to induce the light source to irradiate the light beam onto the target sample side. Done.

In this situation, of course, due to the light source side light irradiation, the light output from the target sample side passes through the refraction surface 61a of the lens group 61 and the convex surface 61b convex toward the pinhole stop 53 side, Pass through the pinhole 63a of the pinhole aperture 63, and pass through the refractive surfaces 104a, 104b, 105a, 105b of the camera lens group 104, 105, and then through each surface 103a, 103b of the optical filter 103. Then, it reaches the pixel of the image sensing unit 102, and undergoes a process of forming an image into a series of <enlarged sample images>. Consequently, as in each of the foregoing embodiments, the user side, at any time, at any time Flexibility to enjoy the effect of easily expanding the desired target sample can be enjoyed.

Specific embodiment data of the microscope optical lens system 60 according to another embodiment of the present invention described above is given in Table 17 (wherein, the material forming the lens group 61, NBK7 of Schott Co. (As shown in the aspherical surface of the camera lens group 104,105, and its aspherical surface constant, see Korean Patent No. 545068).

Here, the pinhole 63a of the pinhole aperture 63 has a diameter D of 0.2 mm, as shown in Table 17, and satisfies the conditions shown in Equation 1 above, and the lens group 61. ) / Camera lens groups 104 and 105 have a total refractive power p of 0.294 while having a distance t of 5.59 mm from the first refractive surface 61a to the last refractive surface 105b from the data presented in Table 17 above. In the case of mm ⁻¹ (in this case, the refractive power of only the lens group 61 is 0.069 mm ⁻¹ ), it satisfies the condition shown in Equation 4 above.

Under the data given in Table 17, as shown in FIG. 12, the sample magnification image finally formed in the image sensing unit 102 is C-line (656.3 nm), d-line (587.6 nm), e- Spherical aberration within the range of about 0.31 mm is shown over each wavelength of light such as line (546.1 nm), F-line (486.1 nm), and g-line (435.8 nm).

In addition, the sample magnification image finally formed in the image sensing unit 102, as shown in FIG. 12, exhibits distortion aberration having a maximum size of about 1.33%.

As such, in another implementation environment of the present invention, the sample magnified image finally formed in the image sensing unit 102 can be seen that the optical aberration is generally well corrected, as shown in FIG. 12.

While irradiating, the pinhole aperture 63 / lens group 61 / camera lens group 104,105 assembly is moved to provide a distance between the target sample and the first refractive surface 61a of the lens group 61.

Is adjusted to 5.5 mm to 12.0 mm (of course, in this case, the total refractive power of the lens group 61 and the camera lens group 104, 105 satisfies the constraint set forth in Equation 4 above). As shown in Table 18, the distance from the last refractive surface 105b of the camera lens group 104,105 to the image sensing unit 102 to form an image of a magnified image is longer or longer according to the above-described operation. It can be seen that the change undergoes a shortening continuously, and accordingly, the magnified image that is finally formed in the image sensing unit 102 also increases or decreases by 1 to 10.8 times or continuously changes. Can be.

On the other hand, as shown in Fig. 13, under another embodiment of the present invention, the optical lens system 70 for a microscope, unlike the previous embodiment, the lens group 71, 74 to the pinhole aperture 73 With the interposed therebetween, the structure is arranged one by one on the front and rear thereof (wherein, a detailed description of the pinhole aperture 73 with the pinhole 73a will be replaced with the above-mentioned details).

Of course, even in this case, the pinhole aperture 73, the lens groups 71 and 74, the camera lens groups 104 and 105, etc., if necessary, form a structure that is fixed and connected to each other to allow the same movement. In the situation, the lens groups 71 and 74 and the camera lens groups 104 and 105 maintain their total refractive power within a certain range, so that the degree of refraction of the light rays passing through the pinhole 73a of the pinhole aperture 73 (eg, The angle of refraction), and thereby, the light beam does not spread (in this case, a detailed description of the pinhole aperture 73 having the pinhole 73a will be replaced with the above-mentioned details). box)

Of course, in the arrangement of the lens groups 71 and 74 and the camera lens groups 104 and 105, when the degree of refraction (eg, angle of refraction) of the light beam is adjusted within a predetermined range, the light beam passing through the pinhole 73a is itself. In spite of the influence of phosphorus intrinsic property or pinhole 73a, the spreading width can be reduced, and thus, the magnified image that is finally imaged on the image sensing unit 102 has various optical aberrations, for example, spherical aberration. (Spherical aberration), astigmatism (distortion), distortion aberration (Distortion aberration) and the like can be corrected well.

Even in this case, in the present invention, in consideration of occurrence of the above-described problems, the total refractive power of the lens groups 71 and 74 and the camera lens groups 104 and 105 is maintained in the range shown in Equation 4 above. By doing so, by normally suppressing the spread of the light rays passing through the pinhole 73a, the sample magnified image finally formed in the image sensing unit 102 may be induced to have good optical aberration.

On the other hand, in another embodiment of the present invention, when it is necessary to adjust the magnification of the sample magnification image, the user operates the various electronic devices, such as a motor, a shaft, a gear, driving the lens driving inducing devices, In the aftermath, the pinhole diaphragm 73 / lens group 71,74 / camera lens group 104,105 assembly of the present invention can continuously move away from or close to the target sample.

Of course, even in this situation, the distance from the camera lens group 104,105 to the image sensing unit 102 is in accordance with the movement of the pinhole aperture 73 / lens group 71,74 / camera lens group 104,105 assembly described above. Longer or shorter changes may be continuously experienced, and thus, the magnified image that is finally formed in the image sensing unit 102 may also be continuously enlarged or reduced.

As a matter of course, even under such an implementation environment of the present invention, on the user side using the electronic device, the electronic device is operated to operate the target sample, the pinhole diaphragm 73 / lens group 71, 74 / camera lens group ( 104,105) With only a very simple measure of adjusting the distance between the assemblies close or far, it is possible to freely continuously adjust the magnification of the magnified image finally formed in the image sensing unit 102 (in this case, If omitted as necessary, the microscope optical lens system 70 of the present invention can effectively provide a magnification image of a fixed magnification in which optical aberration is well corrected).

On the other hand, under another system of the present invention, if the user carries the electronic device and needs to observe the target sample, the electronic device approaches the target sample, and the microscope optical lens system 70 provides the target sample. Induces access to and then manipulates the power supply (e.g., operates a power supply switch) so that power on the power source side is supplied to the light source side, thereby taking action to induce the light source to irradiate the light beam onto the target sample side. Done.

Of course, in this situation, due to the light source side light irradiation, the light rays output from the target sample side are the refractive surfaces 71a and 71b of the lens group 71, the pinhole 73a of the pinhole aperture 73, and the lens. After passing through the refractive surfaces 74a and 74b of the group 74 and passing through the refractive surfaces 104a, 104b, 105a and 105b of the camera lens groups 104 and 105, the respective surfaces 103a and 103b of the optical filter 103 are Passing through, reaching the pixels of the image sensing unit 102, and undergoing a process of forming an image into a series of <enlarged sample images>. As a result, as in each of the foregoing embodiments, the user side, at any time and at any time, is desired. Flexibility to enjoy the effect of easy magnification of the target sample is provided.

Specific implementation data of the optical lens system 70 for a microscope according to another embodiment of the present invention described above is given in Table 19 below (wherein, the material constituting the lens group (71, 74), Schott Co., Ltd.) NBK7 is optionally used) (see Korean Patent No. 545068 for the aspherical surface details and the aspheric constants of the camera lens groups 104 and 105).

As can be seen, accordingly, it can be seen that the sample enlarged image finally formed in the image sensing unit 102 also causes a change that is enlarged or reduced by 1 times to 10.7 times.

In addition to the above-described various embodiments, the present invention can make various changes depending on circumstances.

For example, as shown in FIG. 15, the optical lens system 80 for a microscope of the present invention includes camera lens groups 104 and 105, and unlike the previous embodiment, the lens group 81 is mounted with a pinhole aperture ( It is also possible to take a structure in which one sheet is disposed on the rear surface of 83 (in this case, the detailed description of the pinhole stop 83 provided with the pinhole 83a will be replaced with the above-described details).

As another example, as shown in FIG. 16, another microscope optical lens system 90 of the present invention includes a camera lens group 104, 105, and unlike the previous embodiment, the lens group 91, 94 is selected. It is also possible to take a structure in which two consecutive pairs are arranged on the front surface of the pinhole stop 93 (the detailed description of the pinhole stop 93 provided with the pinhole 93a will be replaced with the above description. ).

As another example, as shown in FIG. 17, the optical lens system 110 for a microscope of the present invention includes a camera lens group 104 and 105, and unlike the previous embodiment, the lens group 111 and 115 may include a pinhole aperture ( It is also possible to take a structure in which two consecutive pairs are arranged on the rear surface of 113) (the detailed description of the pinhole diaphragm 113 having the pinhole 113a will be replaced with the above-described details).

Of course, in each of the embodiments of the present invention, through the pinholes (83a, 93a, 113a) self-equipped, the pinhole apertures (83, 93, 113) and the pinhole aperture to reduce the width of the light incident from the target sample side A lens group (81,91,94,111,115) that reduces optical aberration of the sample enlarged image by preventing the light rays passing through the pinhole apertures (83,93,113) from being selectively disposed in front of or behind the (83,93,113). And the camera lens groups 104 and 105, and the same movement of the pinhole apertures 83, 93, 113, the lens groups 81, 91, 94, 111, and 115, and the camera lens groups 104, 105 as necessary. In such a fixed state, by adjusting the distance between these assemblies and the target sample, the magnification of the sample magnification image can be continuously controlled, so that the lens system for a microscope can be used even under another implementation environment of the present invention. (80,90, On the 110) side, under the <simple structure in which the lens and the pinhole aperture are simply combined>, rather than the conventional complex structure in which a plurality of objective lenses and alternative lenses are linked, a variety of magnifications of the high quality clear sample magnification image are variously enlarged. It is possible to adjust and provide at a magnification, and eventually, it becomes possible to naturally realize the reduction of its size and the expansion probability of the arrangement of the circuit module for linking external devices, and as a result, through the linkage with other electronic devices, It will be able to flexibly serve as a sample enlargement device to improve the function of A.
