Description
Technical field
The present invention relates to technical field of medical instruments, particularly relate to a kind of examination of ocular fundus camera lens.
Background technology
In prior art, for checking that the camera lens on optical fundus mostly is combination type, general by illumination optical lamp, single formula aspheric surface connects order object lens and micro-imaging object lens combinationally use, if in use do not have illumination optical lamp to connect order object lens to single formula aspheric surface irradiate and provide light source, micro-imaging cannot complete.Above-mentioned compound lens, complex structure, volume is large, and be a monoblock type after debugging assembles, user cannot carry out assembly and adjustment flexibly, very flexible between assembly.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of examination of ocular fundus camera lens, convenient disassembly, applies in a flexible way, and replaceability is strong.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of examination of ocular fundus camera lens, comprise: aspheric surface connects order object lens, light optics focusing group and micro-imaging objective lens, the rear connecing order object lens in described aspheric surface arranges light optics focusing group, described micro-imaging objective lens is arranged on the rear of light optics focusing group, described light optics focusing group comprises reflecting mirror, flash lamp, infrared transmitter, focusing lens group and focusing motor, described reflecting mirror is positioned at the lower left of focusing lens group, described flash lamp, infrared transmitter is positioned at immediately below reflecting mirror, described focusing motor is positioned at the top of focusing lens group,
Described flash lamp, infrared transmitter send infrared ray and reflex to aspheric surface by reflecting mirror and connect order object lens, then connect through aspheric surface the optical fundus that the projection of order object lens enters eyeball; Connect the imaging of order object lens by the Infrared of fundus reflex through aspheric surface, carry out focusing by focusing lens group and reduce or amplification imaging size, then by the imaging of micro-imaging objective lens.
In a preferred embodiment of the present invention, coordinate versatility stronger for what make examination of ocular fundus camera lens and other adnexa, the rear of micro-imaging objective lens is provided with control circui line port, and described control circui line port is connected with the digital camera of infrared receiver.
The invention has the beneficial effects as follows: aspheric surface is connect order object lens, light optics focusing group and micro-imaging objective lens and is integrated into a camera lens by the present invention, eliminate the assembly mode that original illumination optical lamp needs work in combination, the configuration of illumination optical lamp is built in camera lens, operator only needs replacing examination of ocular fundus camera lens, can assembling be completed, easy to operate.
