ABSTRACT:
This invention concerns a fundus camera which can take photographs other than by fluorescence or by fluorescence. An optical device is withdrawn from the optical path of a photographic system at the same time as a barrier filter for taking photographs by fluorescence is inserted and is inserted in the optical path of the photographic system for observation purposes at the same time as the barrier filter is removed. The optical device has the same optical path length as the barrier filter, and thus a focused fundus image attained during observation is not upset when fluorescent photographs are taken.
