PROBLEM TO BE SOLVED: To reduce astigmatism generated by a beam splitting member such as a dichroic mirror.SOLUTION: An ophthalmologic apparatus includes a projection optical system configured to project a light flux on a subjects eye, a beam splitting member configured to form a split optical path corresponding to a light flux from the subjects eye, and an image-forming optical system configured to receive via the beam splitting member a light flux from the subjects eye, the image-forming optical system including an optical element having an optical characteristic that reduces astigmatism generated by the beam splitting member.COPYRIGHT: (C)2014,JPO&INPIT【課題】ダイクロイックミラー等の光分割部材により発生する非点収差を低減すること。【解決手段】眼科装置が、被検眼に光束を投影する投影光学系と、被検眼からの光束に対し、分岐した光路を形成する光分割部材と、被検眼からの光束を光分割部材を介して受光する結像光学系であって、光分割部材により発生する非点収差を低減する光学特性を持つ光学素子を備える結像光学系と、を有する。【選択図】図1
