applied to isolate different physical environments while allowing light to pass through. When selecting windows, it's impossible to consider materials, transmission, scattering, wavefront distortion, parallelism and resistance to certain environment. we provide all kinds of windows, which are made from different materials. Windows of special sizes and materials are available upon requirement. Single layer or multiplayer antireflecting or high-reflecting coatings on optical windows are available upon requirement.
