DETERMINING THE SUITABILITY OF AN OPTICAL MATERIAL FOR THE PRODUCTION OF OPTICAL ELEMENTS, CORRESPONDING DEVICE, AND USE OF SAID MATERIAL

摘要

The invention relates to a method for determining the suitability of an optical material that is to be used for the production of optical elements, particularly for high-energy light irradiation. According to the inventive method, radiation-induced absorption in the optical material is determined by radiating said optical material with excitation radiation and determining the total fluorescence which is induced by means of said radiation and comprises intrinsic and non-intrinsic portions, the non-intrinsic fluorescence during and/or immediately following radiation being determined as fluorescence. The invention also relates to a corresponding device and the use of the material which is tested in said manner.
