ABSTRACT:
A method for reducing the scattered light emitted through an optical element is provided that protects adhesive used to hold the optical element in place from light induced deterioration. In one embodiment, the method includes applying a thin coating of an organoxy metallic compound to a region on an optical element where adhesive will be applied and exposing the organoxy metallic compound to ultra-violet light. Exposure to ultra-violet light converts the organoxy metallic compound to its corresponding metal oxide forming an optically inert, light absorbing coating that protects adhesive used to hold the optical element in place from light induced deterioration.
