<P>PROBLEM TO BE SOLVED: To provide a corneal image focused over the whole range of photography range while securing the wide range of photography. <P>SOLUTION: In the corneal microscope apparatus, the corneal image is obtained by enlarging and photographing a part of the cornea of an examined eye. The corneal microscope apparatus comprises an anterior ocular segment observation optical system for observing the anterior ocular segment of the examined eye from the front; an illumination optical system having an illumination light axis for obliquely projecting a slit beam toward the cornea of the examined eye to focus a slit image on the cornea of the examined eye; and an imaging optical system having an imaging light axis for receiving reflection light obliquely from the cornea with the observation light axis of the anterior ocular segment observation optical system in-between to guide the light to an image sensor, and having a slit located at a position conjugated with the slit image via a light receiving lens. The illumination light optical system and the imaging optical system are optically disposed so that the image face of the slit image formed on the cornea of the examined eye by the illumination optical system and the image face of the slit formed on the cornea of the examined eye by the imaging optical system are on the same face. <P>COPYRIGHT: (C)2009,JPO&INPIT |
