Mirror
Mirror is a reflecting surface that forms an image of an object when light rays coming from that object fall upon it. Usually mirrors are made of plate glass, one side of which is coated with metal or some special preparation to serve as a reflecting surface.
UPT offers dielectric coated mirrors and metal coated mirrors which are made of substrate such as Bk7, K9, Fused Silica, CaF2, Sapphire.
