The wafer/windows can be manufacture by material of fused silica(JGS1/JGS2/JGS3).
Optical 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. When selecting windows, you should consider the following: material, transmission, scattering, wave front distortion, parallelism and resistance to certain environment.
optical window 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.
Optical windows by BK7 glass,fused silica,sapphire and float glass,B270 glass and so on.Dimension
depends on your requirement.
We offer 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.
