Abstract
A light source device includes a plurality of light emitters, an optical system configured to combine light from the light emitters, a wavelength selective filter located on an optical path of the optical system, and an optical sensor configured to receive light from one light emitter among the light emitters through an optical filter. The optical filter has a wavelength selection characteristic corresponding to a wavelength selection characteristic of the wavelength selective filter.
