WINDOWS

Windows are optical glass normally with polished faces that are relatively parallel. They are used to protect laser output. Windows are often AR coated to minimize reflection. AR coated windows offer improved transmission when used in industrial displays or computer monitors. The high transmission makes them ideal for most industrial and laser protecting applications.
