Abstract:
A light source device includes a wavelength conversion element adapted to emit a second light in a first wavelength range due to irradiation of a first light, and a wavelength separation element to which the second light is input, and the wavelength separation element generates a third light reduced in light intensity of a component in a second wavelength range among a component in the first wavelength range compared to the second light.
