Laser Windows

Optical windows are made by optically flat, transparent optical material that allow light into an instrument. Windows have high optical transmission with little distortion of the transmitted signal, but can not change the magnification of the system. Windows are widely used in various optical devices such as spectroscopic equipment, optoelectronics, microwave technology, diffractive optics, etc.

When choosing a window, the user should consider whether the material's transmission properties and the mechanical properties of the substrate are consistent with specific requirements of the application. Coating is another important issue for choosing a proper window. WISOPTIC offer a wide variety optical windows with different coatings, e.g. anti-reflection coated precision windows for Nd:YAG laser applications. If you would like to order a window with a coating of your choice, please specify your request.
