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. 冷鏡熱控濾光片 主要參數
