About Optical Windows
How Optical Windows functions
Optical windows are applied to isolate different physical environments while allowing light to passing through.When selecting windows,it's important to consider materials,transmission, scattering,wave front distortion,parallelism and resistance to certain environment.
Customized Service
C-PE offers all kinds of windows,which are made from different materials.Windows of special sizes and materials are available upon requirement.Single layer or multiplayer anti-reflecting or high-reflecting coatings on optical windows are available upon customer's requirement.
