Abstract
The invention discloses an eye fundus examination camera lens. The eye fundus examination camera lens comprises an aspheric surface eye contact object lens, a lighting optics focusing set and a microimaging object lens set. The lighting optics focusing set is arranged behind the aspheric surface eye contact object lens. The microimaging object lens set is arranged behind the lighting optics focusing set. The lighting optics focusing set comprises a reflecting lens, a flashlight, an infrared light emitter, a focusing lens set and a focusing motor. The reflecting lens is arranged on the left bottom of the focusing lens set. The flashlight and the infrared light emitter are arranged under the reflecting lens. The focusing motor is arranged above the focusing lens set. The infrared ray emitted by the flashlight and the infrared light emitter penetrates through the reflecting lens and reflected to the aspheric surface eye contact object lens, and passes through the aspheric surface eye contact object lens to project into the eye fundus of an eyeball. The infrared light ray reflected by the eye fundus forms an image through the aspheric surface eye contact object lens. Size of the image can be contracted or expanded in a focusing mode by the focusing lens set. And the image is eventually formed through the microimaging object lens set. With the adoption of the structure, the eye fundus examination camera lens can be conveniently dismounted, flexibly applied, and is strong in replaceability.
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, be used for checking that the camera lens on optical fundus mostly is combination type, generally by the illumination optical lamp, single formula aspheric surface connects the order object lens and the micro-imaging object lens are used in combination, do not shine and light source is provided if in use have the illumination optical lamp to connect the order object lens to single formula aspheric surface, micro-imaging can't be completed.Above-mentioned compound lens, complex structure, volume is large, is a monoblock type after debugging assembles, and user can't carry out assembly and adjustment, very flexible between assembly flexibly.
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: a kind of examination of ocular fundus camera lens is provided, comprise: aspheric surface connects the order object lens, light optics focusing group and micro-imaging objective lens, the rear that connects the 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 be positioned at reflecting mirror under, described focusing motor is positioned at the top of focusing lens group,
Described flash lamp, infrared transmitter send infrared ray and connect the order object lens by mirror reflects to aspheric surface, then connect through aspheric surface the optical fundus that the projection of order object lens enters eyeball; Infrared by fundus reflex connects the imaging of order object lens through aspheric surface, and focus by the focusing lens group and dwindle or the 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, be provided with the circuit controling line road port at the rear of micro-imaging objective lens, described circuit controling line road port is connected with the digital camera of infrared reception.
