Stepped Glass Window

Optical windows are fabricated from a variety of substrate materials and many are available either with or without AR coatings. In addition to flat and wedged optical windows, we also offer UV fused silica windows designed to be oriented at 45° AOI, Brewster windows that eliminate p-polarization reflectance, optical ports with integrated UV fused silica windows, and high-vacuum conflats with windows.

Optical Window selection considerations include material transmission properties as well as scattering, strength and resistance to certain environments. Their use should not impact on magnification of a system. Optical Windows can be optically polished and incorporate an element for diffusing light source to control illumination.
AR coatings can be applied to ensure maximum transmission performance for a particular wavelength. The windows are made in a range of materials including UV Fused Silica, Quartz, IR Crystals and optical glasses. Our optical window properties include x-ray protection, non-browning to UV light and light transmission from deep ultra violet to far-infrared.
