Metallic mirrors

Metallic coated mirrors are optical substrates coated with a thin layer of metal. We offer four kinds of metallic coating, the coating reflectance curve as right figure.

►UV Enhanced Aluminum coating:. R>85%@250—700nm

►Protected Aluminum coating: R>85%@400--700nm

►Protected Silver coating: R>94%@350—1000nm

►Protected Gold Coating: R>95%@700—800nm, R>97%@800-2000nm
