Abstract:
An optical assembly and a method for making the optical assembly. The optical assembly includes an optical element; a blocking coating; a capping layer on the 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 capping layer is made from a material having high transmission in the UV and enables use of aggressive cleaning treatments on the optical element significant impairment of the UV transmission of the optical element.
