Fused Silica UHV Laser Viewports With ‘VAR’ Anti-Reflective Coatings

VacTechniche laser viewports are offered with a two-layer ‘VAR’ anti-reflective coating on both sides of the window optimised to a customer specified laser wavelength. The coating reduces reflection to below 0.5% per face or 1% total at the wavelength specified. Please advise the laser wavelength with your enquiry or order.

Wavelengths between 240 nm and 1550 nm can be accepted as standard, although coatings for other wavelengths can be quoted on request. Viewports with coatings or a wavelength range can also be offered. The viewports comprise a high purity laser quality fused ilica optic with precise flatness, parallelism, scratch and dig specifications. The ultra high vacuum UHV) CF versions are offered using high grade 304L or 316LN stainless steel flanges.
