Abstract
A wavelength selection unit includes a light source which emits light of at least a predetermined wavelength region, a collector lens which collects the light emitted from the light source and emits a parallel flux which is inclined relative to a light axis of an optical system of itself, a selective reflection optical system which reflects light of a predetermined wavelength region from the parallel flux selectively, and a returning optical system which returns each reflected flux reflected by the selective reflection optical system symmetrically about a reflected light axis of the selective reflection optical system. The collector lens collects a back flux which is returned by the returning optical system and which is re-reflected by the selective reflection optical system, and forms a light source image of the light source.
