Optical Grade BK7 Sapphire Glass Laser Windows
Optical windows are used to allow optical radiation to pass from one environment to another without allowing other elements of these environments to mix. And it does not change the wavelength distribution of the beam, the transmitted wave front, nor does it scatter any of the light out of the beam.
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.
