ABSTRACT:
A fundus camera includes a first illumination optical system for illuminating the fundus of the eye with infrared light, a second illumination optical system for illuminating the fundus of the eye with visible light used for photography that shares a part of the optical path with the first illumination optical system. A target projection optical system projects a target for focusing on the fundus. An observation optical system is provided with a focusing lens and a photographic element sensitive to infrared, thereby allowing the fundus to be observed. A display mechanism is provided to display an image obtained by the observational optical system. In addition, a mechanism is provided to move the target plate on the optical axis by interlocking the movement of the focusing lens with the observational optical system.
