PROBLEM TO BE SOLVED: To provide an ophthalmic apparatus with an irradiation optical system for irradiating the eyeground of a subject eye with pattern light which is made by using a plurality of light-emitting elements.SOLUTION: The ophthalmic apparatus includes illumination means in which a plurality of pairs of light sources are arranged about an axis of an illumination optical system in a predetermined pattern, each pair of light sources including: a first illumination light source emitting light of predetermined wavelength region and arranged to project an illumination light flux along the optical axis of the illumination optical system and a second illumination light source 91a-91h emitting light of a different wavelength region from that of the first illumination light source and arranged more apart than the first illumination light source from the optical system to project an illumination light flux in a direction approaching the optical system. The ophthalmic apparatus further includes guide members 93a-93h which make the illumination light flux from the second illumination light source of paired light sources coaxial with the illumination light flux from the first illumination light source of the paired light sources, and which guide the illumination light fluxes from both the light sources which are made coaxial along the optical axis toward optical members.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2018,JPO&INPIT【課題】被検者眼の眼底を複数個の発光素子を用いたパターン光で照明する、コンパクトな照射光学系を備えた眼科装置を提供する。【解決手段】所定の波長域の光を発する第1の照明光源であって,照明光学系の光軸に沿って照明光束を照射するように配置される第1照明光源と、第1照明光源とは異なる波長域の光を発する第2の照明光源であって,光軸に対して第1照明光源より離れた位置に配置され光軸に近づく方向に向けて照明光束を照射するように配置される第2照明光源91a~91hと、を一対の光源とし、一対の光源を照明光学系の軸周りに複数並べて所定のパターン状に一体的に配置してなる照明手段を備える。更に、一対とされる一方の第2照明光源から発せられる照明光束を他方の第1照明光源の照明光束と同軸とし,同軸とされた両光源からの照明光束を光学部材に向けて光軸に沿うようにガイドするガイド部材93a~93hを備える。【選択図】図5
