PARAMETER:
Windows are optical glass with ground and polished faces that are relatively parallel. They are used to isolate two physical environments while allowing light to pass,it also can be a protection of original when it's in two physical environments.And there is almost no effect on visible light,to coat on the surface of windows could increase the transmittance,the commonly used coatings are antireflection coating (AR) and scratch-resistant coating(AS).Windows with coating can enhance the light penetration strength,and own function of waterproof ,dustproof,and scratch-proof.They are mainly used in mobile screen and lens protection,digital camera, digital video recorders, industrial optical windows, touch screen products, GPS products, digital electronic products windows, car rearview mirror, computer screen, laptop screen, watch surface and so on.
BRD OpticalProvide all types of windows made from different materials. Special size and materials are also available upon request. In addition, we provide a variety of single layer or multiplayer anti-reflecting coating on optical windows.
