LIGHT RESISTANCE TESTING MACHINE AND METHOD

摘要

PROBLEM TO BE SOLVED: To provide a light resistance testing machine capable of achieving higher life predicting accuracy by setting the test environment to be close to an actual using environment.;SOLUTION: The light resistance testing machine 300 continuously collects test light L and illuminates a sample 100 of an optical element used for an optical device with test light L, and promotes and evaluates the light resistance of the sample 100. The light resistance testing machine comprises a light source 310 having a luminescence wavelength characteristic equivalent to that of the light source in actual use of the optical device, a light shielding shutter 320 for adjusting light quantity of the test light L radiated to the sample 100, an integrator optical system 350 for uniforming the illuminance distribution of the test light L, and a condenser lens 370 for collecting the test light L and illuminating the light receiving face of the sample 100 with it.;COPYRIGHT: (C)2007,JPO&INPIT
