China Optical Sapphire Glass Dia. 81.26mm*21.5mm Windows Flat

Production Description
* Picture show of our optical windowWhat is optical window?Optical Windows are flat, plane-parallel, transparent optical surfaces designed to protect sensors and other electronic instruments from environment conditions.

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.

Optical window can be a protection of original when it's in two physical environments. And there is almost no effect on visible light,to coating on the surface of windows could increase the transmittance,the commonly used coatings are antireflection coating (AR) and scratch-resistant coating(AS).Optical glass flat with coating can enhance the light penetration strength,and own function of waterproof ,dustproof,and scratch-proof.

Optical windows are typically fabricated from two flat, or commonly referred to as plano, polished surfaces that are optically transparent and intended to separate, seal, or otherwise protect other components. The double-sided manufacturing process yields exceptional parallelism and transmitted wavefront making it ideal for visible windows in industrial and biomedical applications, as well as IR windows in infrared and military/defense applications.

It's one of optical window customized by our customer, we could also manufacture and design other optical window as per your requirement.
