Fused Silica UHV Viewports With Anti-Reflective Coatings

VacTechniche fused silica viewports are offered with a single 1 x QWOT MgF2 layer anti-reflective (AR) coating on both sides of the window optimised to a customer specified wavelength range. Please advise the important wavelengths or wavelength range with your enquiry or order.

Wavelength ranges between 190 nm and 1550 nm can be accepted as standard, although coatings for other wavelength ranges can be quoted on request. Viewports with ‘V’ coatings for a single wavelength for laser applications and four-layer broadband low reflectance ‘BBAR’ coatings are also offered. The viewports comprise a high purity laser quality fused silica optic with precise flatness, parallelism, scratch and dig specifications.
