Abstract

A light source device includes a light source main unit made of a combination of a plurality of semiconductor laser devices, a plurality of collimator lens respectively capable of converting light beams emitted by the respective semiconductor laser devices of the light source main unit to respective approximately parallel light beam fluxes, and a condenser lens capable of condensing light beam fluxes emitted by the plurality of collimator lenses. The light source main unit has the plurality of semiconductor laser devices arranged, when viewed from the condenser lens, so that the stems of the adjacent semiconductor laser devices are seemingly continuous in a first direction perpendicular to the optical axis of the condenser lens, and the stems of the adjacent semiconductor laser devices are overlapped in a second direction perpendicular to both the direction of optical axis and the first direction.
