What is an optical window? The function and principle of an optical window
Optical windows are planar, parallel, transparent optical surfaces designed to protect sensors and other electronics from environmental conditions. Optical window selection considerations include material transmission properties as well as scattering, strength, and resistance to certain environments. Their use should not affect the magnification of the system. The optical window can be optically polished and contains an element for diffusing the light source to control the illumination.
Anti-reflection coatings can be applied to ensure greater transmission performance at specific wavelengths. Windows are made from a variety of materials including UV fused silica, quartz, infrared crystals, and optical glass. Optical window properties include X-ray protection, non-browning to UV light, and light transmission from deep UV to far infrared.
Optical window products include wedges, substrates, discs, planes, plates, protective windows, laser windows, camera windows, light guides and more.
Windows are used by scientific and industrial companies in medical, defense, instrumentation, laser, research and imaging.
