Claims

[Scope of utility model registration request]

(1) In the observation optical path, the fundus image of the subject formed by the louver passes sequentially through a fixed mirror, a sliding mirror, and an eyepiece lens to an inverted mirror configured so that it can be observed as an enlarged inverted image. An indirect mirror characterized by being provided with a plurality of illumination systems.

(2) Multiple reflection mirrors and illumination lenses installed on the side of the light source in the lamp housing form multiple illumination optical paths, and the illumination optical paths pass through the illumination mirrors and illumination lenses, and then pass through the louver to the subject. An indirect imaging mirror according to claim 1, which is a utility model, and is configured to illuminate the fundus of the eye as a plurality of illumination fields.
