Abstract
A fundus camera, for taking photographs by fluorescence, has an illuminating optical system to illuminate a fundus. The illuminating optical system is provided with a diaphragm that can be adjusted to modify the illumination state of the fundus according to the light reflected from the fundus when taking photographs by fluorescence. As a result, a good photographic image of the fundus can always be obtained.
