Abstract

The embodiment of the invention provides an aging device of an optical element. The aging attenuation test device of the optical element provides irradiation light source to the optical element through a light source module, and the optics transmittance attenuation test of the optical element is performed in the irradiation of the light source. In the process of the optics transmittance attenuation test, optical powers of the light source irradiation of the optical element can be received at different times through a first power detection module, a power regulation module regulates the light source module according to the optical powers of the light source irradiation of the optical element can be received at different times to allow the optical element to become aging in the illumination of the stable optical power, and an optical measurement device such as a spectrometer and the like can be used for match measurement to obtain the attenuation case of the optics transmittance in the light irradiation of the stable optical power after the optical element is subjected to illumination aging.
