Description

A kind of stereomicroscope using integral type four sides reflecting prism

Technical field

A kind of stereomicroscope is the utility model is related to, it is especially a kind of using the stereoscopic aobvious of integral type four sides reflecting prism Micro mirror.

Background technology

Common stereomicroscope has the characteristics of several important：First, eyepiece and object lens are angled, people can be seated Eyes can be under viewing objective against eyepiece sample；Second, under object lens sample imaging light by after two eyepieces The eyes of observer are imaged at the same time, thus need the distance by two groups of light paths separated after object lens to change into the double of suitable people The distance of eye；Third, eye-observation to sample imaging be erect image just meet people observe sample custom；These three are important Feature is played an important role by the prism group between object lens and eyepiece, and prism group is more by the way of combination at present, such as The patent " low depression-angle microscope " of my company's application（The patent No. 201020195207.6）：It is by certain three different prisms Mode compose an overall prism group, achieve the purpose that light path steering, light path distance of separation, inverted image change into erect image；But this The glued mode of kind also has the shortcomings that processing technology is complicated, production cost is high, the bad control of bonding quality.

The content of the invention

Technical problem to be solved in the utility model is to provide a kind of using the stereoscopic aobvious of integral type four sides reflecting prism Micro mirror, is integrally formed prism by integral type processing technology, it is equal to possess the prism group formed with three pieces of prism cementings Function, and solve the shortcomings of cemented prism group processing technology is complicated, production cost is high, bonding quality bad control.

The utility model solve its technical problem the technical scheme adopted is that stereomicroscope eyepiece and object lens it Between employ left integral type four sides reflecting prism 3 and right integral type four sides reflecting prism 4 each one, the institute of sample 7 on base 8 is anti- The light penetrated passes through beam splitting system again after object lens 6, and left light is anti-into left integral type four sides by left incident light joint chair 9 Prism 3 is penetrated, left incident light 13 has carried out four secondary reflections by four faces inside it, and most rear left emergent light 21 connects by left eyepiece Seat 11 reaches left eyepiece 1；Right wing light enters right integral type four sides reflecting prism 4, right incident light by right incident light joint chair 10 22 have carried out four secondary reflections by four faces inside it, and most rear right emergent light 30 reaches right eyepiece 2 by right eyepiece joint chair 12； In this way, left and right two-way light completes light path steering, light path distance of separation, inverted image change into erect image, human eye is from eyepiece at this time The erect image of sample 7 can be observed.

The beneficial outcomes of the utility model are that this uses the stereomicroscope of integral type four sides reflecting prism, passes through one Change processing technology to be integrally formed prism, possess the equal function of the prism group formed with three pieces of prism cementings, and solve The shortcomings of cemented prism group of having determined processing technology is complicated, production cost is high, bonding quality bad control.

Embodiment

The utility model is further illustrated with reference to the accompanying drawings and examples.

As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, left integral type is devised between the eyepiece and object lens of stereomicroscope Four sides reflecting prism 3 and right integral type four sides reflecting prism 4 each one, the light that the sample 7 on base 8 is reflected pass through object lens Left integral type four sides reflecting prism 3, left incident light 13 are entered by left incident light joint chair 9 by beam splitting system, left light after 6 Four secondary reflections are carried out by four faces inside it, most rear left emergent light 21 reaches left eyepiece 1 by left eyepiece joint chair 11；It is right Road light enters right integral type four sides reflecting prism 4 by right incident light joint chair 10, and right incident light 22 passes through four inside it Face has carried out four secondary reflections, and most rear right emergent light 30 reaches right eyepiece 2 by right eyepiece joint chair 12；Due to left incident light 13 and a left side The angle of the angle of emergent light 21 and right incident light 22 and right emergent light 30 is designed to the folder with object lens axle center and eyepiece axle center Angle is equal, it is thus achieved that light path turns to, people can be seated by the sample 7 under eyepiece viewing objective；Due to light path design The distance between axle center of reason, the axle center of left incident light joint chair 9 and right incident light joint chair 10 will be much smaller than two eyepiece axle center The distance between, and two groups of incident rays enter left integral type four sides by left incident light joint chair 9, right incident light joint chair 10 respectively After each have passed through four secondary reflections after reflecting prism 3, right integral type four sides reflecting prism 4, this two groups are entered before eyepiece The distance of light is adapted with two eyepieces, realizes separating for two optical path distances, there is imaging in eyes；Furthermore Incident light have passed through the turnover of four secondary reflections, and the inverted image of sample 7 has changed into erect image, so as to reach eye-observation to sample erect image Purpose.

In Fig. 4, the moving line of left light is direction shown in arrow in figure, is according to left incident light 13, turns left to roll over Light（One）15th, left-hand rotation refractive power（Two）17th, left-hand rotation refractive power（Three）19th, the order of left emergent light 21, in left integral type four sides reflection rib 3 internal reflection of mirror four times, their normal is left normal respectively（One）14, left normal（Two）16, left normal（Three）18, Zuo Fa Line（Four）20.

In Fig. 5, the moving line of right wing light is direction shown in arrow in figure, is according to right incident light 22, folding of turning right Light（One）24th, right-hand rotation refractive power（Two）26th, right-hand rotation refractive power（Three）28th, the order of right emergent light 30, in right integral type four sides reflection rib 4 internal reflection of mirror four times, their normal is right normal respectively（One）23, right normal（Two）25, right normal（Three）27, right method Line（Four）29.

Particular embodiments described above, is only the preferred embodiment of the utility model, all according to the utility model Shen Please the equivalent arrangements done of the scope of the claims, the technology that should be the utility model covered.
