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.
 
Innowit offers all types of windows made of different materials. Special size and materials are also available upon request. In addition, we provide various coating on optical windows.
 
 
We can supply different windows made from below materials.
