COATING WITH ADHESION LAYER FOR UV OPTICS
First Claim
1. An optical assembly comprising:
- an optical element;
a holder for the optical element;
a blocking coating positioned between the optical element and the holder, the blocking coating including a light absorber that does not transmit light with wavelengths from greater than or equal to about 190 nm to less than or equal to about 500 nm;
an adhesion promoter positioned between the light absorber and the optical element; and
an adhesive configure to adhere the optical element to the holder;
wherein the light absorber is positioned such that light having a wavelength from greater than or equal to about 190 nm to less than or equal to about 500 nm is not incident to the adhesive.

Abstract
An optical assembly and a method for making the optical assembly. The optical assembly includes an optical element; an adhesion promoter; a blocking coating; a holder; and an adhesive configured to adhere the optical element to the holder. The blocking coating includes a light absorber that does not transmit light with wavelengths from greater than or equal to about 250 nm to less than or equal to about 400 nm; The light absorber is positioned such that light having a wavelength from greater than or equal to about 190 nm to less than or equal to about 500 nm is not incident to the adhesive. The adhesion promoter improves adhesion of the blocking coating to the optical element and reduces the likelihood of delamination during handling, operation, or clearing of the optical assembly.
