Abstract:
1. An ophthalmologic photographing apparatus comprising: 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, an optical axis of the reflected light flux from the eye being inclined with respect to an optical axis of the illuminating light into the eye; 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 an optical axis of the reflected light flux when the reflected light flux is incident on the imaging device, wherein the imaging surface of the imaging device is shifted, due to the first optical member, from a position following a Scheimpflug principle as a function of a reduction in the imaging incidence angle.
