Round optical glass windows(K9 CaF2,MgF2,Ge,ZnSe,Mono Si,ZnS,quartz)s

Optical windows refer to a piece of transparent optical material that allows light into an optical instrument. They are pieces of optical glasses with ground and polished faces that are relatively parallel. Optical windows are applied for protecting fragile optical components inside an equipment, they are adopted to isolate two physical environments while allowing light to pass.
