Abstract

See full text

A light source apparatus includes a light source configured to emit first light, a wavelength converter configured to emit second light having a wavelength different from that of the first light, a first optical system, and a second optical system configured to transmit the second light. The second optical system includes a reflector configured to reflect the first light to the wavelength converter. The first optical system condenses the first light from the light source on the wavelength converter, and guides the first light to the reflector.
