Abstract
The utility model relates to a stereo microscope, including a lever and an optical path reflection unit, wherein the lever is connected to the reflection unit, and the optical path reflection unit comprises a rotary reflection mirror and a reflection prism. The angle between the upper housing and the lower housing has a regulating range between 0 DEG and 35 DEG, the incident light ray emitted by the observed object is transmitted outside through the lower housing and the upper housing after injected into object lens, angle between two incidence rays 2 alpha is 12 DEG. By regulating the angle between the upper and lower housing, the utility model uses lever to drive the reflection unit for synchronous opposite regulation, so that the object of adjustable observation angle of microscope is reached. Consequently, not only cervical vertebra fatigue of observer due to long time observation is avoided, and efficiency is enhanced. The utility model has great stability, will not cause viewed image change in angular regulation, and is in accordance with principle of man-machine engineering.
Description
Technical field
The utility model relates to a kind of microscope, especially a kind of stereomicroscope of scalable viewing angle.
Background technology
Microscope is in the process of using, observer's eyes are observed the image of object by eyepiece, angle between observation eyepiece and the surface level, be commonly called as " viewing angle ", because the difference of Human Physiology and the difference of workplace, need different viewing angles and adapt with it, common stereomicroscope has two types fixedly viewing angle, is respectively 45 ° or 60 °.
Known microscopical viewing angle depends primarily on the angle of reflecting prism, owing to the angle of reflecting prism is fixed, so known microscopical viewing angle also is changeless.
The utility model content
The utility model can not free adjustment at existing microscopic examination angle, and when observing use for a long time, can make the people feel uncomfortable, cause cervical vertebra fatigue easily, influence the healthy problem of people, provide a kind of angle regulator project organization simple, when observing use for a long time, can not make and cause cervical vertebra fatigue, and can not influence the healthy stereomicroscope of people.
For achieving the above object, the utility model provides a kind of stereomicroscope, described eyeglass is arranged at described enclosure interior, described housing comprises upper shell and lower house, article two, incident ray is injected after described upper shell is propagated to upside by the lower house of object lens, also comprises lever and light path reverberator, and described lever is connected with described light path reverberator, and be arranged between described upper shell and the described lower house, the angle range of adjustment between described upper shell and the lower house is 0 °～35 °; 2 α angles of described two incident ray angles are 8 °～15 °.
2 α angles of described two incident ray angles are 12 °
Described upper shell inside is provided with eyepiece, Guan Jing successively, turns to prism and intermediate mirror.
Described light path reflector element comprises rotation reflective mirror and reflective prism.
Described reflective prism and rotation reflective mirror are set in turn between the described intermediate mirror of described Guan Jingyu.
Compared with prior art, the utlity model has following advantage:
The novel a kind of stereomicroscope that provides of this reality is provided with lever and light path reflector element in enclosure interior, lever is connected with the light path reflector element, the light path reflector element comprises rotation reflective mirror and reflective prism, angle range of adjustment between the upper and lower casing is 0 °～35 °, incident ray is injected after upper shell is propagated to upside by the object lens lower house, and two incident ray angle 2 α angles are 12 °.The utility model is by regulating the angle angle that goes up between the lower house, thereby make lever and reflector element carry out locking phase to angular adjustment, and can keep that view image does not distort, displacement in the eyepiece visual field, reach the adjustable purpose in microscope visualization angle.The observer can regulate viewing angle according to self range estimation height in angle of regulation range, to keep comfortable observation posture, not only avoided owing to the long-time cervical vertebra fatigue that causes of observing, also improved observation efficiency, be fractographic developing direction, can predicting in a short period of time, stereomicroscope all can generally adopt the continuously adjustable observing system of viewing angle; In addition, the utility model is simple in structure, and good stability can not make in carrying out the angular adjustment process that view image distorts, displacement in the eyepiece visual field, thereby more meets the principle of ergonomics.
Description of drawings
The optical system diagram that Fig. 1 adopts for the utility model;
Fig. 2 is the utility model external structure synoptic diagram;
Fig. 3 is an external structure synoptic diagram after the utility model angular adjustment.
The main element symbol description is as follows:
1 intermediate mirror, 2 reflective mirrors
3 reflective prism 4 pipe mirrors
5 turn to prism 6 eyepieces
7 upper shells, 8 lower houses
9 incident raies, 10 object lens
Embodiment
Fig. 1 is the optical system diagram that the utility model adopts, and mainly comprises intermediate mirror 1, reflective mirror 2, reflective prism 3, pipe mirror 4, turns to prism 5, eyepiece 6, object lens 10 and incident ray 9.Reflective mirror 2, reflective prism 3 are arranged between pipe mirror 4 and the intermediate mirror 1.The incident ray 9 that two angles that send from observed object are 2 α, this incident ray 9 is via object lens 10 and intermediate mirror 1 directive reflective mirror 2 surfaces, inject again and turn to prism 5 via managing mirror 4 by reflective prism 3 through reflective mirror reflection back, after in turning to prism, carrying out 90 ° turn back, propagate to the opposite side edge by a side, then after the another side that turns to prism carries out 90 ° turning back, enter observation eyepiece with vertical direction, observer's eyes by eyepiece with observed project objects to the retina of eyes, close picture back from obtaining a stereopsis that is in this object of limited distance.
When being incident to reflective mirror 2 reflections by intermediate mirror 1 after, light injects reflective prism 3, when pulling angle that upper shell carries out 0 °～35 ° and change, reflective mirror 2 in upper shell also produces an angle variation with the upper shell interlock by lever, the image of observed object still can be remained in the eyepiece visual field do not distort, displacement.
Fig. 2 and Fig. 3 are respectively the utility model angular adjustment front and back external structure synoptic diagram, mainly comprise upper shell 7 and lower house 8.Lever (among the figure describe) is arranged between upper shell 7 and the lower house 8, and lever is connected with reflective mirror and reflective prism, when upper shell 7 is regulated by lever, has also driven the rotation of reflective mirror and reflective prism.Can change microscopical viewing angle by upper shell 7 is regulated, the range of adjustment of this viewing angle is in 0 °～35 °, and can regulate continuously.In continuous adjustment process, the image of object still can remain in the range of observation of eyepiece 6, the image of object is distorted, displacement.
In sum, the stereomicroscope that the utility model provides by pulling the binocular in the upper shell up and down, can drive lever synchronously and reflective mirror rotates, thereby reach the purpose that user's viewing angle is regulated.Because reflective mirror can link according to certain relation and reflecting prism, thereby the angle variation after taking place in the angle that guarantees to rotate reflective mirror, and the image of object still can remain in the range of observation of eyepiece, and the image of object is subjected to displacement.The utility model is simple in structure, and good stability can not make in carrying out the angular adjustment process that the object image of observing distorts, displacement in eyepiece, thereby more meets the principle of ergonomics.
More than disclosed only be several specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
