发明名称 Ophthalmic photographic apparatus
摘要 An ophthalmic photographic apparatus includes an illumination optical system for illuminating an eye fundus and a photographing optical system for photographing an image of the illuminated eye fundus. The ophthalmic photographic apparatus includes a first aperture stop, a second aperture stop having an outside diameter that is smaller than that of the first aperture stop, a third aperture stop that transmits more light than the first aperture stop, and means for selectively inserting the first to third aperture stops into the optical path of the illumination optical system. The ophthalmic photographic apparatus does not have a complicated structure, but can be readily used in the various photographing modes.
