Abstract:
An optical filter 11 is fixed in an optical path in a light generation unit 6 to cut out light in an infrared region. The optical filter 11 do not deviate from the optical path, and infallibly eliminate light in the infrared region which becomes heat radiation. The optical filter 11 cuts out light whose wavelength is longer than a threshold wavelength that is longer than 805 nm and shorter than 815 nm, and eliminates heat radiation in the infrared region, which includes a wavelength (approximately 825 nm) which is substantially a first peak P of the radiant intensity of the xenon lamp 10.
