PROBLEM TO BE SOLVED: To provide an eyeground imaging apparatus having a compact illumination optical system which suppresses superimposition of noise light on captured images.SOLUTION: The eyeground imaging apparatus includes: an illumination optical system 30 for illuminating the eyeground of a subject eye and an imaging optical system 10 for capturing an image of the eyeground illuminated by the illumination optical system. The illumination optical system includes a plurality of illumination light sources 31 or 32 for illuminating the eyeground of the subject eye, which are arranged annularly around the optical axis of the imaging optical system between an objective lens 11 and an imaging element 17 of the imaging optical system. First iris portions to regulate the illumination light fluxes from the illumination light sources are arranged respectively at positions substantially conjugate with the pupil and the crystalline lens of the subject eye in the light path of the illumination optical system.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】撮影画像へのノイズ光の重畳を抑制したコンパクトな照射光学系を備えた眼底撮影装置を提供する。【解決手段】被検者眼の眼底を照明するための照明光学系30と、照明光学系により照明された眼底を撮影する撮影光学系10とを備える眼底撮影装置において、照明光学系は、被検者眼の眼底を照明するための複数の照明光源31または32を持ち、複数の照明光源は撮影光学系が持つ対物レンズ11と撮像素子17との間にて撮影光学系の光軸周りに環状に配置し、且つ、照明光源から発する照明光の光束を制限するための第1絞り部を、照明光学系の光路における被検者眼の瞳孔,及び水晶体と略共役となる位置に各々配置する。【選択図】図2
