Abstract
An anterior segment photographing apparatus comprises a slit light beam projecting system for projecting a slit light beam on an eye to be examined, an image forming optical system disposed right in front of the eye to be examined and capable of forming an image of a section of the anterior segment of the eye represented by the slit light beam reflected from the eye on a light receiving, a concave mirror having a concave reflecting surface in a shape of rotational symmetry with respect to the optical axis of the image forming optical system and capable of collecting and reflecting the reflected slit light beam reflected from the eye, and a reflecting mirror for reflecting the reflected light reflected from the concave mirror toward the image forming optical system.
