Abstract
The filter transmits a light beam of a second wavelength emitted from each of a plurality of second light sources, reflects other light beams incident from a direction intersecting a traveling direction of the light beam of the second wavelength, and outputs a combined light of the light beam of the second wavelength and the other light beams. The first optical element transmits part of the light beam of the first wavelength emitted from the first light source or part of the light beam of the second wavelength included in the combined light output from the filter, and reflects the other light beams excluding the part thereof in the direction intersecting the traveling direction. The first light receiving element receives the part of the light beam of the first wavelength transmitted by the first optical element or the part of the light beam of the second wavelength.
