Abstract

A continual zoom demonstration microscope is mainly composed of a three-layer panel frame, an eye lens disk, an objective lens disk, a liner sliding rail, triple prisms, a power source control box, a light source and a focusing objective table. The three-layer panel frame is composed of three layers of supporting table panels. The eye lens disk is provided with an eye lens, an analog signal ccd (AV signals), an electric eye lens (digital signals), a digital camera interface (connected with a digital camera to perform micrograph). The objective lens disk is provided with a microscope objective lens. The middle layer supporting table panel is provided with the linear sliding rail and four triple prisms, wherein two triple prisms are fixed, and the other two triple prisms are driven through the linear sliding rail. The distances among the triple prisms are changed, namely the distance between the eye lens and the objective lens is changed, and a continual zoom effect is achieved. The eye lens disk and the objective lens disk are combined to achieve the demonstration and the observation of different objects. Proper magnification times are chosen according to actual demands to perform observation, demonstration, photograph and the like. Due to the continual variation of the magnification times, the optimization of the observation effect can be achieved.

Description

Continuous zoom demonstration microscope

Technical field

The utility model relates to a kind of microscope, more specifically says a kind of microscope that can realize continuous zoom, and is convenient to use in teaching demonstration process.

Background technology

Microscope is the important instrument in the fields such as biology, medical science.Existing microscope enlargement factor is all fixed, can not continuous zoom, some object observing is less at low power Microscopic observation, and target may disappear after changing high power lens, need again find, find the rear target may be larger again, while particularly carrying out photomicrograph, be inconvenient to select the target of suitable size.Existing microscope does not integrate the functions such as photograph, demonstration, uses very inconveniently in teaching demonstration, does not have to connect the microscope of digital signal electron eyepiece again by connecting analog signal video camera yet.

Utility model content

The purpose of this utility model is: provide a kind of and can overcome above-mentioned defect, energy continuous zoom, object observing is amplified continuously, both can obtain the image that enlargement factor is higher, can select the image of suitable size to take again, demonstrate, storage etc., its successful is better than existing microscopical continuous zoom demonstration microscope.

The technical scheme that the utility model technical solution problem adopts is: continuous zoom demonstration microscope comprises three layer flat plate framework, eyepiece dish, object lens dish, line slide rail and prism, power control box, light source, focusing objective table: described three layer flat plate framework is comprised of three layers of brace table panel, every layer of brace table panel is all long 380 millimeters, the metal plate of wide 240 millimeters, it is characterized in that upper strata brace table panel has the circular hole of 20 millimeters of diameters, this installs rotatable eyepiece dish (a positive anistree dish) above brace table panel, described eyepiece dish has four holes, difference installation microscope eyepiece, electronic eyepiece (digital signal), simulating signal (AV signal) ccd and camera interface, during use, allow one of them aim at the circular hole of upper strata brace table panel, described middle level brace table panel also has the circular hole (relative with the circular hole of upper strata brace table panel) of 20 millimeters of diameters, rotatable object lens dish (being also a positive anistree dish) is installed below the brace table panel of described middle level, described object lens dish has four holes, the micro objective of different multiples is installed respectively, during use, allow one of them aim at the circular hole of middle level brace table panel, above the brace table panel of described middle level, line slide rail and prism are installed, described lower layer support deck plate, as base, is provided with focusing objective table, light source and power control box etc. on it.

The beneficial effects of the utility model are: between upper strata and middle level brace table panel, utilize four prisms, utilize prism principle of reflection to change optical path direction; Two prisms are fixed, and another two prisms utilize line slide rail to drive, and regulate the distance between prism, realize the change of eyepiece and object lens spacing, reach continuous zoom effect; The rotation of eyepiece dish and object lens dish makes different camera lens combinations, adapts to the needs of different object observings and demonstration, can detect by an unaided eye, and can show by TV, projector, can also take pictures by digital camera.

In figure, 1. prism I, 2. prism II, 3. prism III, 4. prism IV, 5. eyepiece dish, 6. object lens dish, 7. eyepiece, 8. object lens, 9. sample, 10. focusing objective table, 11. light sources, 12. three layer flat plate frameworks, 13. eyepiece dish bearing rotating shafts, 14. microscope ocular mounting holes, 15. simulating signal ccd mounting holes, 16. electronic eyepiece mounting holes, 17. digital camera interface, 18. object lens mounting holes, 19. object lens dish bearing rotating shafts.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further illustrated.

1, on eyepiece dish, there are microscope ocular mounting hole 14, simulating signal (AV signal) ccd mounting hole 15, electronic eyepiece mounting hole 16, digital camera interface 17.According to service condition and observation, demonstration, photograph needs, rotation eyepiece dish 5, selects above-mentioned a certain structure to aim at the circular hole on the brace table panel of upper strata.Select microscope ocular mounting hole 14 to detect by an unaided eye by eyepiece 7; Select simulating signal (AV signal) ccd mounting hole 15 micro-image can be become to simulating signal (AV signal) connecting TV etc.; Select electronic eyepiece mounting hole 16 micro-image can be become to digital signal, input computer; The interface 17 of choosing a digital camera connects digital camera and carries out photomicrograph.

2, the micro objective 8 of different amplification is installed on object lens dish 6, and target sizes needs according to the observation, the circular hole of selecting a certain object lens 8 to aim on the brace table panel of middle level by gig mirror disk 6, find image process and focus adjustment method similar to the operation of simple microscope, no longer describe in detail.

3, line slide rail and prism above the brace table panel of middle level are used for realizing zoom effect, according to prism principle of reflection, change optical path direction; Have four prisms, prism I1 changes over level by the vertical optical path of object lens 8, through prism I I2 prism I I I3, light path is mapped to prism IV4, prism IV becomes optical routing horizontal direction vertical direction directive eyepiece 7 again, prism II2 prism III3 drives by line slide rail, by four-headed arrow direction in Fig. 1, moves, and continuously changes the distance between the two and prism I1 prism IV4, the distance that changes 8, eyepiece 7 and object lens, realizes continuous zoom effect; This scheme can be selected suitable enlargement factor according to actual needs, observes, demonstrates, photograph etc.

4, by the combination between eyepiece dish and object lens disc spins and camera lens, realize demonstration and the observation of different target, due to the continuous variation of enlargement factor, can reach the optimization of observing effect.
