Optical Window - Bk7 & Fused Silica, 6mm-132mm Diameter, Ar Coated For High Transmission And Laser Protection

Optical Windows

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