发明名称 Opthalmic apparatus for judging alignment conditions based on target images
摘要 An ophthalmic apparatus having measurement device for inspection or measurement, and bringing the measurement device into the predetermined positional relationships relative to an eye to be examined, the ophthalmic apparatus providing a moving device for moving the measurement device relatively to the eye to be examined, an alignment target projecting optical system for projecting plural alignment targets onto the periphery of cornea of the eye to be examined, an alignment target detecting optical system for detecting target images which are formed by projecting the alignment targets, a judging device for judging the alignment condition in vertical and lateral direction based on the number and positional relationships of target images which are detected, and an instruction device for instructing the moving device to move based on the result judged by the judging device.
