The invention provides a fundus camera imaging and lighting system. The system sequentially comprises human eyes, an objective lens, a first reflector, a second reflector, a collecting lens, a lighting circular ring, an imaging lens group and an image acquisition device from left to right. In a lighting optical system, light emitted by the lighting circular ring sequentially passes through the collecting lens, the first reflector, the second reflector, a hole in the first reflector and the objective lens and then reaches the human eyes. In an imaging optical acquisition system, imaging light of the human eyes sequentially passes through the objective lens, the hole in the first reflector, a hole in the second reflector, a hole in the collecting lens, a hole in the lighting circular ring and the imaging lens group and then reaches the image acquisition device. A fundus camera imaging system and a lighting system are ingeniously combined together, stray light is eliminated, the structureis compact, and various optical indexes are achieved.
Description
technical field [0001] The invention relates to the technical field of a fundus camera, in particular to a fundus camera imaging and lighting system. Background technique [0002] With the development of medical level, there are more and more detection devices for human eyes. Among them, when performing human eye inspection, it is necessary to image the eye. When the fundus photography system is used for fundus imaging, the light source needs to enter the human eye, and the light reflected by the human eye is received for imaging analysis. The existing illumination optical system and imaging optical acquisition system are relatively complex, which is not conducive to the acquisition of human eye images. Contents of the invention [0003] The present invention aims at at least solving the technical problems existing in the prior art, and particularly innovatively proposes a fundus camera imaging and lighting system. [0004] In order to achieve the above-mentioned purpos...
