Customized High Precision Optical ND 50 Glass Windows From China

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. 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.
