Abstract

The invention discloses a binocular fundus camera. The binocular fundus camera comprises a left eye piece, a right eye piece, an illuminating system and a photography system which are arranged in a camera body of the fundus camera, wherein the illuminating system is arranged among a light source of the fundus camera, the left eye piece and the right eye piece, and the illuminating system is used for dividing light rays emitted by the light source into two paths to enter double eyes through the left eye piece and the right eye piece respectively; the photography system comprises an optical assembly and a camera assembly, the optical assembly is arranged among the camera assembly, the left eye piece and the right eye piece, and light rays reflected back from the fundus of a to-be-examined eye pass through the left eye piece and the right eye piece and then pass through the optical assembly and are transferred to the camera assembly for imaging. The binocular fundus camera can achieve theeffect of simultaneously shooting the left and right eyes of a same person through one-time positioning and one-time operation.

Description

technical field [0001] The invention relates to the technical field of ophthalmic optical instruments, in particular to a binocular fundus camera. Background technique [0002] The fundus camera is an important ophthalmic optical instrument, and has become one of the necessary instruments in ophthalmology. Modern people suffer from diabetes and other related diseases involving fundus lesions, and all of them require early detection and early treatment. Existing fundus cameras can only take pictures of one eye, and cannot take pictures of two eyes at the same time through one operation. Contents of the invention [0003] The object of the present invention is to provide a binocular fundus camera to solve the above-mentioned problems in the prior art. Through one positioning and one operation, the fundus camera can photograph the left and right eyes of the same person. [0004] In order to achieve the above object, the present invention provides the following scheme: the p...
