Protected Silver Mirror With SiO2 Overcoat for Visible & IR

Evaporated Metal Films (EMF)

Protected Silver Mirrors with Thickness 2.0

Protected Silver Mirror

EMF’s protected silver mirrors are used in high reflectance applications in the visible and infrared spectrum. EMF’s protected silver mirrors have an overcoat of SiO₂ to increase durability and to meet the adhesion, abrasion, temperature and humidity requirements of MIL-M-13508C. Although the overcoat is helpful in protecting the silver layer from tarnishing, EMF’s protected silver mirrors are not recommended for use in high humidity environments.
