摘要：PURPOSE:To provide a device automatically performing the optical axis matching and focusing of a photographing system and capable of measuring the cornea thickness concurrently with endothelial photographing when the cornea endothelial cells of a testee are enlargedly photographed. CONSTITUTION:The cornea reflected image of the alignment light projected to the eyeball face 2 coaxially with the optical axis 4 of a front eye ction obrving optical system is picked by a television camera 8. A photographing system 3 constituted of an obrving optical system, an illumination system slit-illuminating the eyeball face 2 slantly, and an enlargement photographing optical system forming the enlargement image of an inspected ction with the television camera 8 bad on the illumination light is automatically moved in the X, Y-directions relative to the optical axis 4 so that a light spot on a photographing screen by the reflected light falls on the prescribed position of the screen. When the light spot falls on the prescribed area of the screen, the advance of the photographing system 3 is started while the light spot is followed in the optometrical direction, the focusing of the cornea epithelium and cornea endothelium is detected by a light receiving element 30 via an optical path parate from the television camera 8, the cornea endothelium of the inspected ction inlargedlyphotographed, and the cornea thickness is measured.
