PROBLEM TO BE SOLVED: To provide an ophthalmologic apparatus capable of appropriately suppressing an influence of an image being rotated when luminous flux is rotated.SOLUTION: An ophthalmologic apparatus includes a base optical system 7L, an optical member 85, and a rotation part 81L. The base optical system 7L includes at least either an emission part for emitting luminous flux or a light reception part for receiving the luminous flux. The optical member 85 has optical power and is provided on an optical path between the base optical system 7L and an eye to be examined. The rotation part 81L changes luminous flux on an eye-to-be-examined side extending from the optical member 85 to the eye to be examined by rotating the luminous flux at a rotation position S between the optical member 85 on the optical path and the base optical system 7L. A main rotation axis MO, which is a rotation axis of the luminous flux by the rotation part 81L when changing the luminous flux on the eye-to-be-examined side in a main changing direction crossing an optical axis of the optical member 85, is perpendicular to a reference optical path 2KL extending from the rotation position S to a base optical system 7L side.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2020,JPO&INPIT【課題】光束を旋回させることによって像が回転する影響を適切に抑制することが可能な眼科装置を提供する。【解決手段】眼科装置は、ベース光学系７Ｌ、光学部材８５、および旋回部８１Ｌを備える。ベース光学系７Ｌは、光束を出射する出射部、および、光束を受光する受光部の少なくともいずれかを備える。光学部材８５は、光学的パワーを有すると共に、ベース光学系７Ｌと被検眼の間の光路上に設けられる。旋回部８１Ｌは、光路上における光学部材８５とベース光学系７Ｌの間の旋回位置Ｓにおいて光束を旋回させることで、光学部材８５から被検眼へ向けて延びる被検眼側光束を変更する。光学部材８５の光軸に交差する主変更方向に被検眼側光束を変更する際の、旋回部８１Ｌによる光束の旋回軸である主旋回軸ＭＯが、旋回位置Ｓからベース光学系７Ｌ側へ延びる基準光路２ＫＬに対して垂直である。【選択図】図６
