Fundus camera lighting system and fundus camera

Abstract

The present invention provides a fundus camera lighting system and a fundus camera. The fundus camera lighting system comprises at least one light source and a light reflecting structure; the light source is arranged inside a lens cone and positioned on one side of a central axis inside the lens cone; and the light reflecting structure is arranged in the lens cone, opposite to the light source andused for reflecting light rays emitted by the light source out, and after the light source passes through an eye piece group or an eye piece objective lens arranged in the lens cone, the light sourceimages outside the lens cone. Compared with the internal illumination mode in the prior art, the fundus camera light system does not need to independently arrange parts outside the lens cone, and thefundus camera is smaller in size and simpler to assemble.

Description

technical field [0001] The invention relates to the technical field of fundus cameras, in particular to a fundus camera lighting system and a fundus camera. Background technique [0002] As the visual organ for human beings to perceive the world, the eyes form an inverted real image on the retina through the eye optical system, and the optical signals are converted into optic nerve signals and sent to the brain system. As the only tissue in the whole body that can observe blood vessels and their distribution under living and non-invasive conditions, the retina has become an important window for diagnosing eye diseases and related systemic diseases. Not only can it diagnose the most common ophthalmic diseases, but it can also diagnose diseases such as high blood pressure, diabetes, and thrombosis at an early stage (systemic diseases, especially blood-related diseases, will be reflected in the fundus tissue). [0003] The most important fundus optical imaging detection instru...

Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the existing fundus camera with internal lighting method, which needs to separately install components such as light collecting mirrors outside the lens barrel, resulting in the technical defects of large volume and complicated assembly of the fundus camera, thereby providing a fundus camera that does not need A fundus camera lighting system that makes the fundus camera compact and easy to assemble by separately installing parts outside the lens barrel
