| description | PROBLEM TO BE SOLVED: To provide a light source device of high efficiency capable of coping with a high output, a wide area, multiwavelength and the like. SOLUTION: This light source device 1 includes a light source 10 for emitting the first light, a reflector 12 for reflecting the first light to be advanced along a prescribed direction, and an emitter 11 arranged within a light beam of the first light emitted from the reflector 12, and for emitting the second light along the prescribed direction. The second light is advanced along the direction substantially same to that of the first light, since the emitter 11 is arranged within the light beam of the first light. The first light and the second light are easily guided to the substantially same area to be irradiated, an optical system is simplified thereby in an optical path from the light source device to the area to be irradiated. A light loss is remarkably reduced in the optical system, and the light source device of high efficiency is provided by this manner. COPYRIGHT: (C)2010,JPO&INPIT |
