Abstract

A light with higher luminance is radiated while lights of a plurality of different wavelengths are appropriately selected and light guiding efficiency is improved. An illumination apparatus including three or more light sources which are arranged so that optical axes of the light sources intersect at one point and which respectively emit lights of different wavelength ranges, an optical device which transmits a light from one of the light sources while reflecting lights from the other light sources so as to make the lights enter an optical path of the light from the one of the light sources, and an optical device rotator which rotates the optical device in a direction in which the light sources are arranged.
