Abstract
The utility model discloses a continual zoom-stereo microscope optical system, which comprises objective lenses and a compensating lens of a continual zoom-stereo microscope main system, wherein a large objective lens combined by two sets of lenses is mounted in front of light paths of the objective lenses and the compensating lens, the numerical aperture of the large objective lens is the largest magnification numerical aperture of the objective lens in the continual zoom-stereo microscope main system, the entrance pupil distance of the large objective lens is minus 100 millimeter, so that the large objective lens and the two zoom objective lenses of the microscope form a coaxial system. Compared with microscopes in prior art, the continual zoom-stereo microscope has an increased usage range and diversified functions.
Description
Technical field
The utility model belongs to the microtechnic field, is specifically related to a kind of continuous zoom stereomicroscope optical system.
Background technology
The continuous zoom stereomicroscope is a micro display system equipment commonly used; But additional big object lens are expanded microscopical usable range through additional big object lens on the continuous zoom stereomicroscope, make the microscope functions variation; There is more technical matters in it; How to confirm structural parameters, numerical aperture, the entrance pupil position of object lens, the characteristics of optical characteristics etc. are one of directions of prior art personnel research.
The utility model content
The purpose of the utility model be to provide a kind of with big object lens on the continuous zoom stereomicroscope, increased microscopical usable range, make the diversified continuous zoom stereomicroscope of microscope functions optical system.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts: this continuous zoom stereomicroscope optical system; Object lens and compensating glass with continuous zoom stereomicroscope system of subject; It is characterized in that: be provided with big object lens before the light path of said object lens and compensating glass by two groups of combination of lensess; The numerical aperture of big object lens is the numerical aperture of the maximum multiplying power of object lens in the continuous zoom stereomicroscope system of subject, and the interpupillary distance of going into of big object lens is-100mm to make said big object lens and microscopical two change times object lens form a coaxial system.
Adopt the beneficial effect of technique scheme: this continuous zoom stereomicroscope optical system is before the light path of the object lens of existing continuous change times stereomicroscope system of subject and compensating glass, to be provided with the big object lens by two groups of combination of lensess; Enlarge the numerical aperture of additional big object lens; Confirm the entrance pupil position, form a coaxial system to additional big object lens and microscopical two change times object lens.The product nu of microscope object space aperture angle and refractive index is called " numerical aperture "; Represent that with NA when the aberration correction of microcobjective was in margin tolerance, its resolution had only determined the numerical aperture of object lens; Can know by formula: δ=0.61 λ/NA, the wavelength of used light when λ is observation; NA is a numerical aperture of objective, and the numerical aperture of confirming additional big object lens can make the numerical aperture of the multiplying power of frequent work have more satisfied result of use for selecting the numerical aperture of the maximum multiplying power of main body object lens like this.The interpupillary distance of going into of object lens is-100mm greatly, and it is for becoming the entrance pupil position of 3.3 times of times object lens multiplying powers, and other multiplying power can obtain balanced treatment like this, can make the multiplying power of frequent use be in optimum condition again.Design with this structural approach 0.3 times, 0.5 times, 0.7 times, 1.8 times TX160 times of continuous zoom stereomicroscope utilization, all obtains better effects.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
Embodiment
Continuous zoom stereomicroscope optical system as shown in Figure 1 has the object lens and the compensating glass of continuous zoom stereomicroscope system of subject, is provided with the big object lens by two groups of combination of lensess before the light path of said object lens and compensating glass.M is an object plane; N is the additional big object lens of two groups of combination of lensess; B is the object lens and the compensating glass of continuous zoom stereomicroscope system of subject, and O ' is microscopical object point when not adding additional big object lens, and O O ' is the optical axis of additional big object lens; O ' O1 and O ' O2 are the optical axises of main microscope, and this two optical axis included angle is 12 °.The numerical aperture of big object lens is the numerical aperture of the maximum multiplying power of object lens in the continuous zoom stereomicroscope system of subject, and the interpupillary distance of going into of big object lens is-100mm to make said big object lens and microscopical two change times object lens form a coaxial system.
