Multilayer Anti-Reflective Coating Development for PMMA Fresnel Lenses

Abstract

Anti-reflective (AR) coatings comprised of several layers of oxide and nitride dielectric materials have successfully been sputter deposited on UV transparent polymethylmethacrylate (UVT-PMMA) windows. The amorphous coatings are deposited using reactive sputtering in a custom-designed magnetron sputtering tool. The AR coatings are adherent, radiation hard, and improve the transmission of UVT-PMMA windows by approximately 5% in the 300-450 nm range. The coatings will be applied and tested on UVT-PMMA Fresnel lenses for use in space-borne telescopes.
