>> Product Description
Optical Windows are flat, plane-parallel plates that are often used as protective barriers for electronic sensors or detectors from outside environments.Optical Windows should be selected based on the material transmission or mechanical properties of the substrate.
Optical Windows do not cause change in the magnification of a system.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.
VY Optics Photoelectric Technology Co., Ltd.Offers 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.
