Description

Optical structure of microscope

This creation relates to the technical field of microscopes, especially an optical structure suitable for microscopes.

Generally, a known microscope has an objective lens and a set of eyepieces. A piece of light enters the objective lens and passes through the internal optical path of the microscope to the group of eyepieces, which helps to observe an object. Because the internal optical path of the microscope is fixed, the depth of field observed by this set of eyepieces is insufficient to clearly present the stereoscopic image.

In order to solve this problem, the creator of this case proposed a new microscope, applied for and obtained Taiwan's new patent cases such as M565552 and M582828.

In the '552 case, the microscope has two cameras. These cameras reciprocate in a straight line, adjusting the depth of field to achieve different imaging ranges, which can eliminate the dark effect on the periphery of the image.

Based on the microscope in the '552 case, the '828 case was added with a focal length adjustment structure.

The author of this case was not complacent and continued to study the technology of the microscope, and finally developed an optical structure suitable for the microscope.

The main purpose of this creation is to adopt the structure of changing the optical path, so that the two cameras are converted from a linear arrangement to a parallel side-by-side, which effectively improves the convenience of the operation of the microscope, adjusts the viewing angle and magnification, and obtains a macroscopic or microscopic stereoscopic vision.

Due to the achievement of the above purpose, the microscope provided in this creation is equipped with an optical structure on a hardware. The optical structure includes: a first camera and a second camera in parallel, the lenses of the first and second cameras face the same side of the hardware; two sets of first reflection units, the first reflection unit of the group is provided with a Reflecting surface, the reflecting surface maintains a certain angle with respect to the lens of the first camera or the second camera; a group of second reflecting units is between two groups of first reflecting units, and the group of second reflecting units has two that maintain the V A mirror surface, each mirror surface facing the reflecting surface; and, an objective lens facing the second reflecting unit of the group.

In this way, the first reflection unit of this creation changes the optical path of the optical structure, making the first camera parallel to a second camera, effectively improving the convenience of microscope operation, adjusting the viewing angle magnification with the second reflection unit, and obtaining macroscopic or microscopic Stereoscopic vision.

In order to make the purpose, features and advantages of this creation more obvious and easy to understand, here are one or more preferred embodiments, which are described in detail in conjunction with the accompanying drawings as follows.

FIG. 1 is a perspective view illustrating a preferred embodiment of the microscope 10, with an optical structure and a third camera 24 disposed on a hardware.

In the figure, the hardware includes a bottom plate 12 protected by a casing (not shown), a main board 14 and a set of sub-boards 16. The main board 14 stands on the bottom plate 12 and is fixed. The set of sub-boards 16 is combined with the bottom plate 12 and Located on both sides of the motherboard 14.

The optical structure includes a plurality of cameras, a plurality of reflection units, a lens 50 and a light source 52.

Among them, these cameras are defined as a first camera 20 and a second camera 22. The first camera 20 and the second camera 22 are imaging devices equipped with a Charge Coupled Device (Charge Coupled Device, abbreviated as CCD). Two imaging devices are provided. The bottom plate 12 is fixed, and the two are juxtaposed in parallel on both sides of the sub-plate 16 of the group. The first camera 20 and the second camera 22 each have a lens 21 and 23, and these lenses 21 and 23 are on both sides of the main board 14.

It is then seen that these reflection units are divided into two groups of first reflection units 30 and a group of second reflection units 40, and the group of second reflection units 40 is between the two groups of first reflection units 30.

Among them, the first reflection unit 30 of the group has a frame 32, the frame 32 is firmly attached to the bottom plate 12 and a lens 34 with a reflection surface 36 is attached to the first camera 20 (or the second camera 22) The lens 21 (or 23) is in front and at a certain angle.

The objective lens 50 is a lens, which is embedded in the bottom plate 12 and directly faces the second reflection unit 40 of the group and the light source 52 that is not easy to fall off the main board 14.

FIG. 2 is a perspective view showing that the second reflection unit 40 of the group is composed of a support frame 41, a transmission rod 42, a motor 43, a mirror base 46 and two reflection mirrors 47. In the figure, the support frame 41 and the motor 43 are firmly fixed on the main board 14. The transmission rod 42 is erected on the support frame 41 and connected to the rotor (not shown) of the motor 43. The mirror base 46 is combined with a movable base 45, which is connected to the transmission rod 42 through a coupling member 44, so the transmission rod 42 supports the mirror base 46 to move back and forth relative to the main board 14 in the direction of arrow 49 in FIG. 3, which can be adjusted Imaging range (also called Depth of Field, abbreviated as DOF). By means of adhesion, two reflecting mirrors 47 are attached to both sides of the lens holder 46 to maintain two V-shaped mirror surfaces 48, each mirror surface 48 facing the reflecting surface 36.

FIG. 3 is a front view of the second reflecting unit 40, showing that two incoming rays 54 pass through the mirror surface 48 of the reflecting mirror 47 to form two reflecting lines 56 in opposite directions.

FIG. 4 is a schematic diagram showing that two incident rays 54 sandwich a viewing angle 58. When the V-shaped mirror surfaces 48 of the two reflecting mirrors 47 move back and forth between the solid line and the dashed line, the angle of view 58 changes the macroscopic or microscopic stereoscopic field of view with the depth of field adjustment to avoid obstruction of the line of sight.

FIG. 5 is a front view of the microscope 10, showing that the light source 52 is an LED. After the LED is powered on, a beam of light can be emitted to provide the brightness required for the viewing angle 58.

FIG. 6 is a plan view of the microscope 10 and shows that the reflection line 56 entering the reflection surface 36 of the lens 34 becomes a secondary reflection line 51. The first camera 20 (or the second camera 22) receives the secondary reflection line 51 and converts it into an electrical signal output.

Looking back at Figure 1, the third camera 24 performs special spectral imaging applications, such as: indigo green or indocyanine green (ICG) photography.

The ICG referred to here is usually a medical fluorescent dye injected into the human body. After the dye absorbs near-infrared light with a wavelength of 760nm to 780nm, it emits invisible light with an infrared wavelength of 800nm to 850nm, which can be transmitted through a third camera 24 Perform special spectrum image shooting.

Specifically, the third camera 24 is connected to the set of sub-plates 16 and can rotate, so that the third camera 24 passes through the bottom plate 12 and interlaces with the first camera 20 and the second camera 22. A controller 26 is disposed on the main board 14 and connected to the third camera 24. After power-on, the controller 26 operates the lens 25 to swing relative to the bottom plate 12. In particular, the third camera 24 has different magnifications. When the third camera 24 views the whole picture, the detailed structure of the first camera 20 and the second camera 22 is used as an auxiliary.

In FIG. 7, the lens 25 of the third camera 24 is exposed outside the bottom plate, and is located under the microscope 10 (or on the same side) as the objective lens 50.

As such, the microscope 10 of this embodiment has the following advantages:

First, the first reflection unit changes the optical path of the optical structure, causing parallel secondary reflection lines. The secondary reflection is smaller than the single reflection light path space. Not only does the first and second cameras change from a linear arrangement to a parallel arrangement, but the volume of the entire microscope is relatively reduced, the operation is convenient and it is not easy to deflect.

Second, the third camera is in the middle of the microscope, and is used as a special spectrum imaging application, which is different from the normal imaging function of the first and second cameras.

Third, the second reflection unit adjusts the magnification of the angle of view, and can finely adjust the field of view and stereoscopic degree of the observed object.
