Hot/Cold Mirrors
(i)Round
(ii)Rectangle
(iii)Square
Hot Mirrors:
Hot Mirrors is designed to 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.
Cold Mirrors:
The cold mirror is designed to separate heat from light. it reflects the visible and transmits the infrared. Their coatings are all first-surface variety and like the hot mirrors, are also deposited onto low expansion material such as borosilicate glass. These mirrors are usually used at a 45° angle of incidence in randomly polarized light.
