Optical Windows


Windows are applied to isolate different physical environments while allowing light to passing through. When selecting windows, it's necessary to consider materials, transmission, scattering, wave front distortion, parallelism and resistance to certain environment.


MOK optics provides all kinds of windows, which are made from different materials. Special sizes and materials are available upon requirement.
