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. |
