Abstract
The utility model discloses a slit lamp microscope. The slit lamp microscope comprises a lighting lamp, a slit lamp and a light splitter. A transflective prism is arranged behind the light lamp, and an infrared light tube is arranged above the transflective prism. A camera is connected with the lower half portion of the light splitter, and a microscope is connected with the upper half portion of the light splitter. Light rays emitted by the slit lamp are highly concentrated at the focus, the concentrated light rays and infrared light rays refracted from the top of the transflective prism are projected on tissues of an examinee, optical sections of the tissues are displayed through the light splitter and the microscope, and the tissue hierarchy is displayed. By means of the slit lamp microscope, the observation fatigue of pupils can be retarded, and the pupils are in a relax state.
Description
Technical field
This utility model relates to ophthalmic medical instrument technical field, particularly relates to a kind of slit lamp microscope.
Background technology
In prior art, digital microscope with slit lamp (digital type) is the optics examination instrument of ophthalmology routine, can be used to check anterior ocular segment and other intraccular part pathological changes.Owing to adopting halogen tungsten bulb as lighting source, so no matter this instrument all can use in Huo Ming chamber, darkroom, but for detected person after direct-view lighting source is too of a specified duration, easily there is pupil contraction, cause occurring error in testing process.
Utility model content
The technical problem that this utility model mainly solves is to provide a kind of slit lamp microscope, can slow down the fatigue strength of pupil observing, makes pupil in relaxation state.
For solving the problems of the technologies described above, the technical scheme that this utility model adopts is: a kind of slit lamp microscope is provided, slit lamp microscope, comprise: illuminating lamp, slit lamp and beam splitter, it is characterized in that, the rear of described illuminating lamp is provided with semi-transparent semi-reflecting prism, the top of described semi-transparent semi-reflecting prism is provided with infrared lamp, the latter half of described beam splitter is connected with camera, the first half of described beam splitter is connected with microscope, the light being sent by slit lamp is in focus place high concentration, concentrated light and Infrared are incident upon those who are investigated's tissue, microscopy goes out the optical section of these tissues, the level that shows tissue.
The beneficial effects of the utility model are: this utility model utilize pupil that Infrared makes those who are investigated in checking process always in relaxation state, pupil, without contraction, reduces eyestrain degree.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model slit lamp microscope one preferred embodiment.
In accompanying drawing, the labelling of each parts is as follows: 1, illuminating lamp; 2, slit lamp; 3, beam splitter; 4, semi-transparent semi-reflecting prism; 5, infrared lamp; 6, camera; 7, microscope; 8, those who are investigated's (eyes).
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to Fig. 1, this utility model embodiment comprises: a kind of slit lamp microscope, comprise: illuminating lamp 1, slit lamp 2 and beam splitter 3, the rear of illuminating lamp 1 is provided with semi-transparent semi-reflecting prism 4, the top of semi-transparent semi-reflecting prism 4 is provided with infrared lamp 5, the latter half of beam splitter 3 is connected with camera 6, the first half of beam splitter 3 is connected with microscope 7, the light being sent by slit lamp 2 is in focus place high concentration, concentrated light and Infrared are incident upon those who are investigated's tissue, by spectroscope 3 and microscope 7, demonstrate the optical section of these tissues, and the level that shows tissue.
Furtherly, the light that this utility model slit lamp microscope is sent by slit lamp is in focus place high concentration, the tissue that during refracting media of the light of being concentrated through having a look at, only light passes through is illuminated, the position being illuminated just accords with the size and shape of light section, between the two parts that are illuminated and are not illuminated, form obviously contrast, the Infrared simultaneously reflecting from semi-transparent semi-reflecting prism top is incident upon those who are investigated's tissue.There is flexion and reflection during by cornea, crystal, vitreous body in light, they demonstrate the translucent form of light gray, are not dark spaces.When the crack light with narrow is organized by these, operator can demonstrate the optical section of these tissues by spectroscope and microscope, shows the level of tissue, and uses camera record.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes this utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
Claims (1)
1. a slit lamp microscope, comprise: illuminating lamp, slit lamp and beam splitter, it is characterized in that, the rear of described illuminating lamp is provided with semi-transparent semi-reflecting prism, the top of described semi-transparent semi-reflecting prism is provided with infrared lamp, the latter half of described beam splitter is connected with camera, the first half of described beam splitter is connected with microscope, the light being sent by slit lamp is in focus place high concentration, concentrated light and the Infrared reflecting from semi-transparent semi-reflecting prism top are incident upon those who are investigated's tissue, by spectroscope and microscopy, go out the optical section of these tissues, and the level that shows tissue.
