PROBLEM TO BE SOLVED: To provide an optical apparatus which suppresses light quantity unevenness caused by variation in the spectral characteristic of a dichroic mirror occurring depending on the incident angle of incident light.SOLUTION: An ophthalmography apparatus 1a comprises: LEDs 14a and 14b for illuminating an eye being tested E and a dichroic mirror 3 which reflects the light returned from the eye being tested E. The LEDs 14a and 14b illuminate the eye being tested E with illumination light with light quantity unevenness, so as to reduce the light quantity unevenness caused by the spectral characteristic of the dichroic mirror 3 depending on the incident angle of light.COPYRIGHT: (C)2016,JPO&INPIT【課題】入射光の入射角度に依存して生じるダイクロイックミラーの分光特性の変化による光量むらを抑制した光学装置を提供する。【解決手段】眼底撮影装置1aは、被検眼Eを照明するLED14a,14bと被検眼Eからの戻り光を反射させるダイクロイックミラー3とを有し、LED14a,14bは、光の入射角度に依存するダイクロイックミラー3の分光特性により生ずる光量むらを低減するように、光量むらを有する照明光で被検眼Eを照明する。【選択図】図1
