PROBLEM TO BE SOLVED: To provide an ophthalmologic apparatus in which the transition from rough alignment to precise alignment is conducted smoothly and alignment work is efficiently carried out.SOLUTION: An ophthalmologic apparatus 2 that measures an ocular function in a non-contact manner comprises: a plurality of independent Z alignment detection systems 11 and 12 that project alignment light to an eye to be examined, and detect a Z alignment position of the eye to be examined based on the light reflected from the eye to be examined and a control part 56 for controlling the alignment. The plurality of Z alignment detection systems are configured so as to differ in magnification ratio, and the plurality of Z alignment detection systems project the light reflected from the eye to be examined on a common light receiving element 36. The control part is configured so as to perform rough Z alignment on the basis of a signal acquired in the Z alignment detection system of a low magnification ratio of the signals acquired from the light receiving element, and perform precise Z alignment on the basis of a signal acquired in the Z alignment detection system of a high magnification ratio.COPYRIGHT: (C)2014,JPO&INPIT【課題】粗アライメントから精密アライメントへの移行が円滑に行われ、アライメント作業が効率よく行われる様にした眼科装置を提供する。【解決手段】非接触で眼機能を測定する眼科装置2に於いて、被検眼にアライメント光を投光し、被検眼からの反射光に基づき被検眼のZアライメント位置検出を行う複数の独立したZアライメント検出系11,12と、アライメントを制御する制御部56とを有し、前記複数のZアライメント検出系は倍率が異なる様に構成され、該複数のZアライメント検出系は被検眼からの反射光を共通の受光素子36に投影し、前記制御部は前記受光素子から得られる信号の内、低倍率のZアライメント検出系で得られる信号に基づき粗Zアライメントを実行し、高倍率のZアライメント検出系で得られる信号に基づき精密Zアライメントを実行する様構成した。【選択図】図1
