Abstract:
An ophthalmologic photographing apparatus includes: an illuminating optical system for irradiating an examinee's eye with illuminating light; an imaging optical system including an imaging device for receiving a reflected light flux from the eye, the imaging optical system having an imaging optical axis inclined with respect to an optical axis of the illuminating optical system; and a first optical member for reducing an imaging incidence angle, the imaging incidence angle being defined as an angle between a normal direction of an imaging surface of the imaging device and a principal ray of the reflected light flux.
