The conjugate varifocal high multiplying power photoelectric magnifying device comprises a micro light camera head, a collimating lens group, and a connecting cylinder of a lens of a diaphragm. The utility model is characterized in that the internal part of the connecting cylinder of a lens is also provided with a group of secondary amplifying and varifocal components composed of a fixed convergence lens group, a moving divergence lens group, and a micro-regulating convergence lens group. The conjugate varifocal high multiplying power photoelectric magnifying device can be conveniently connected to be a whole body with an output base of a light path of the microscope; through accurate adjustment, the secondary amplifying and varifocal component and a primary image A' of the microscope can mutually coincide, and through the moving divergence lens group, the synthetic focal length of the secondary amplifying and varifocal component can be changed. Accordingly, the magnifying power of the whole conjugate varifocal high multiplying power photoelectric magnifying device can be continuously changed, and the maximum multiplying power of the conjugate varifocal high multiplying power photoelectric amplifying device can reach to 20000 times. The conjugate varifocal high multiplying power photoelectric magnifying device has the advantages of high definition, high resolution, high magnification, etc. The utility model is a novel microscopic magnifying device which has powerful functions and wide application ranges.
Description
The utility model relates to optical instrument, especially a kind ofly be used for microscopical conjugation zoom high magnification photoelectricity multiplying arrangement.
As everyone knows, ordinary optical microscope has been gone through more than 100 year update since invention, but because of being subjected to the restriction of human eye resolution, fits till the present, and its enlargement factor all is no more than 2000 times.For the liquid sample of no dyeing, can only observe with the visual field that is lower than 400 times.Therefore, the field of its application is restricted greatly.For this reason, there is the people that camera is installed on microscope, thereby can makes the maximum transversal enlargement ratio of microexamination increase to 3000 times.Both just like this, still can not satisfy and be used for the trickleer physical form and the observation of inner structure.
The purpose of this utility model is the deficiency that exists at above-mentioned microscope, provides a kind of and can make micro-enlargement ratio reach 20000 times, and can make the conjugation zoom high magnification photoelectricity multiplying arrangement of the clear picture of seeing in the micro-eyepiece.
Conjugation zoom high magnification photoelectricity multiplying arrangement of the present utility model comprises: be provided with the low-light camera head, the lens connecting cylinder on collimation lens set and light hurdle, be nested with the housing that constitutes by large cylinder and bonnet outside the lens connecting cylinder, and the screw that holds out against that is used for lens connecting cylinder location and installation, screw shell, set nut, it is characterized in that: increase by one group and low-light camera head in the lens connecting cylinder, collimation lens set and light hurdle are arranged on same optical axis, by fixing convergent lens group, the secondary that mobile divergent lens group and fine setting convergent lens group constitute amplifies the zoom assembly.
Another feature of the present utility model is: secondary amplifies the mobile divergent lens group of zoom assembly and the light hurdle that the optical axis between the fine setting convergent lens group is provided with adjustable aperture.
Conjugation zoom high magnification photoelectricity multiplying arrangement of the present utility model can link into an integrated entity by screw shell and microscope light path output seat easily, amplify the zoom assembly and microscopically once coincide through accurately regulating secondary as A ', can change the synthetic focal length that secondary amplifies the zoom assembly by mobile divergent lens group, thereby can continuously change the enlargement factor of whole device.Because secondary amplification zoom assembly output directional light and low-light camera head and preposition collimation lens set thereof can be microscopical once as being formed on the low-light camera head, and Flame Image Process is amplified by circuit, thereby see that amplify through secondary and the identical image of target on screen, the image of seeing in this image and the microscope ocular is a conjugate relation.Therefore be simultaneously clearly.Because the synthetic focus of secondary amplification zoom assembly is constant, therefore, when changing multiple, have only the variation of image size, and the sharpness of image can not change substantially again.This device makes microscopical enlargement ratio expand to new multiplying power zone.For medical science, biological study, historical relic, jewel are identified, the research and development in many fields such as metallographic observation of metallurgical industry have increased a kind of means of observing microworld, it has high definition, high degree of resolution, advantages such as high enlargement ratio, be a kind of powerful, the novel micro-multiplying arrangement that has wide range of applications.
Concrete structure of the present utility model is provided in detail by the following drawings and embodiment.
Fig. 1 is the structural representation of conjugation zoom high magnification photoelectricity multiplying arrangement.
Embodiment: can be clear that from Fig. 1, the device case that conjugation zoom high magnification photoelectricity multiplying arrangement is made of large cylinder 16 that is used for 7 installations of lens connecting cylinder and bonnet 17, lens connecting cylinder 7 is provided with support 23, the front end of lens connecting cylinder 7 is fixed by screw 8 and large cylinder 16 end faces, the external part of lens connecting cylinder 7 is plugged in the screw shell 5, is furnished with set nut 6 on the screw shell 5, trip bolt 4 can be connected this device on the microscope light path output seat 3, regulate screw shell 5, then distance between adjustable lens connecting cylinder 7 and the micro objective 2.Lens connecting cylinder 7 and support 23 thereof are positioned in the large cylinder 16 by holding out against screw 15 and 20, bonnet 17 is provided with signal input and output seat 18, be provided with low-light camera head 21, light hurdle 14 and collimation lens set 13 in the lens connecting cylinder 7, scoop up at low-light on the optical axis in picture 21, light hurdle 14 and collimation lens set 13 the place aheads and be provided with by convergent lens group 9, the secondary that divergent lens group 10 and convergent lens group 12 constitute amplifies the zoom assembly, for regulating luminance brightness, can and assemble the light hurdle 11 that adjustable aperture is set between the lens combination 12 in divergent lens group 10.Be provided with light shield 22 between fine setting convergent lens group 12 and the collimation lens set 13.Convergent lens group 9 is fixed in the lens connecting cylinder 7, and divergent lens group 10 is installed for removable mode, and convergent lens group 12 is installed for fine-tuning mode.
During use (referring to Fig. 1), from microscopical object observing 1 is the A point, through 2 one-tenth of micro objectives once as in A ' point, at this moment, by regulating the distance between lens connecting cylinder 7 and the micro objective 2, the front focus that makes secondary amplify the zoom assembly falls within microscope once as on the target surface A ', and by 6 lockings of the set nut on the screw shell 5.Then, by mobile divergent lens group 10, the synthetic focal length of regulating change secondary amplification zoom assembly changes the enlargement factor of this device, what secondary amplified the output of zoom assembly is parallel beam, align collimation lens set 13 and light hurdle 14 again, make and obtain a secondary that amplifies on low-light camera head 21 target surfaces as A "; and will be sent to through the vision signal of processing of circuit and amplification on display or the display monitor central monitoring system; just obtained with target 1 phase conjugate by signal input and output seat 18, but the image of continuous zoom.The horizontal enlargement ratio of target 1 is amplified multiplying power three's the product of multiplying power, low-light camera head and the display thereof of zoom assembly and is determined that the maximum transversal enlargement ratio can reach 20000 times by the multiplying power of micro objective 2, secondary.
