Abstract
A fundus camera includes a light source for observation, and an illiminating optical system having a predetermined illiminating optical axis. The light source for observation illiminates a fundus of an eye via the illiminating optical system. The camera further includes an observation optical system disposed so as to be able to observe the fundus illiminated by the light source for observation, a photographing light source for illiminating the fundus during a photographing operation and disposed on the illiminating optical axis of the illiminating optical system, a photographing system for photographing the fundus illuminated by the photographing light source, and a reflecting member disposed between the light source for observation and the photographing light source on the illuminating optical axis so as to reflect light from the photographing light source in the direction of the fundus during illumination by the photographing light source. The reflecting member is retractable from the illuminating optical axis.
