PROBLEM TO BE SOLVED: To provide a corneal endothelial cell-photographing device which can be downsized, whose structure can be simplified and which can perform accurate and short-time focusing detection.SOLUTION: This corneal endothelial cell-photographing device includes an optical part 3 having an illuminating optical system 11 and a photographing optical system 12, and a focusing mechanism performing focusing detection of the optical part 3 on an eye E to be examined, and is structured as follows: the illuminating optical system 11 includes an illuminating light source 15 for applying slit light to the eye E to be examined from the obliquely front side thereof, and a slit member 17 the photographing optical system 12 has a photographing CCD20 receiving the slit light reflected at the anterior ocular segment of the eye E to be examined from an obliquely front side the focusing mechanism detects the optical part 3 approaching to a focusing position and then the movement in a Z-axis direction of the optical part 3 heading for the eye E to be examined is decelerated or retreated and the focusing detection is performed when the slit light reflected at the anterior ocular segment locates at a prescribed position on the display 20a of the CCD20.COPYRIGHT: (C)2013,JPO&INPIT【課題】小型化及び構造の簡素化が可能となり、正確且つ短時間の合焦検出が可能な角膜内皮細胞撮影装置を提供すること。【解決手段】照明光学系11及び撮影光学系12を含む光学部3と、被検眼Eに対する光学部3の合焦検出を行う合焦機構とを備えており、照明光学系11が、被検眼Eに対してその斜め前方からスリット光を照射するための照明用光源15とスリット部材17とを有しており、撮影光学系12が、被検眼Eの前眼部で反射したスリット光を斜め前方から受光する撮影用CCD20を有しており、合焦機構が、光学部3の合焦位置への接近を検知することにより、被検眼Eへ向かう光学部3のZ軸方向移動を減速又は後退させるように構成されており、上記合焦検出は、前眼部で反射されたスリット光がCCD20の画面20a上の所定位置に位置することによりなされる。【選択図】図1
