ISO 9001 - AS 9100 - ITAR Standard & Custom Optical Filters and Coatings

HOT MIRRORS

Hot Mirrors perform as their name states: they reflect the heat and transmit the visible light. All of the coatings are classified as hard, first-surface dielectric, and will meet or exceed the specified humidity and abrasion specifications. To prevent cracking or crazing from high heat applications, all coatings are deposited onto a low-expansion material such as borosilicate glass.
