Bendable mirrors and method of manufacture

摘要

A heat formable mirror is formed by sputter depositing upon a sheet such as glass a reflective coating utilizing a base layer of silicon or a combination of silicon and stainless steel films, a reflective layer formed of a reflective metallic film such as niobium, titanium or aluminum, and a protective layer comprising preferably silicon nitride. The resulting mirror can be heat formed at elevated temperatures to form a curved mirror having a reflective coating free of objectionable defects.
