    摘要: A light source apparatus includes two or more light sources placed in one direction, and an array lens having two or more lenses, which corresponds to each of the light sources. In order to condense a light emitted from each of the lenses into one position, in a first lens in each of the lenses, an optical axis of the light source which corresponds to the first lens is shifted from an optical axis of said first lens in said one direction. The first lens is formed such that a length from the optical axis to one end of said first lens in the one direction is longer than a length from the optical axis to another end of the first lens in a direction which is opposite to the one direction.

    摘要: A light source device includes a substrate and a plurality of laser light sources. The laser light sources each include a submount mounted on the substrate, and a semiconductor laser element mounted on the submount. The laser light sources are individually and independently disposed on the substrate. The laser light sources disposed adjacent to each other and emitting light having an identical wavelength band differ from each other in thermal resistance at a region between the semiconductor laser element and the substrate.
