Cold mirrors
Description
These cold mirrors have an all-dielectric multilayer coating on a borosilicate glass substrate. They efficiently reflect visible light, while allowing IR radiation to pass through. They have a sharply defined transition between the reflection and the transmission bands. As the absorption is negligible, they can handle high powers.
