PROBLEM TO BE SOLVED: To efficiently conduct a test by an inexpensive facility, and to quickly obtain a test result, when testing a light resistance of an optical component for coping with a specified short wavelength light source. SOLUTION: Light beams emitted from respective light sources are brought once into parallel light beams by respective collimator lenses, using a plurality of the laser beam sources having a wavelength band used for optical pick-up for blue laser or the like, and the parallel light beams are associated thereafter by the second collimator lens of a relatively long focal distance and long diameter, to be convergence-emitted toward the optical component serving as a tested component. The plurality of the laser beam sources and the plurality of collimator lenses enhance light density by arranging those two-dimensionally in parallel. A wavelength as same to one in actual use as possible is used as a wavelength of the light source. COPYRIGHT: (C)2006,JPO&NCIPI
