Abstract
A laminated optical element has an IR transmissive substrate and a laminated IR transmissive polymeric layer on at least one surface of the IR transmissive substrate. The polymer layer may be a fluoropolymer or polyethylene and has an aspheric/diffractive surface. The polymer layer is affixed to the substrate by adhesive or, alternatively, the polymer layer is formed directly on the substrate resulting in a unitary optical element that is IR transmissive.
