ROBUST HIGHLY REFLECTIVE OPTICAL CONSTRUCTION

摘要

An optical construction (20) comprises an optically transmissive substrate (12), an optional adhesion-promoting layer (18) comprising an oxide form of at least one metal or metalloid deposited onto the surface of the optically transmissive substrate (12), a reflective layer (14) composed of a highly reflective metal overlaying the adhesion-promoting layer (18), and a protective layer (16) composed of a parylene polymer film bonded to the reflective m etal layer (14).
