Kodial Zero Length Viewports With Broadband

Anti-Reflective Coatings

Vac Techniche Kodial viewports are offered with a four-layer broadband anti-reflective (BBAR) coating on both sides of the window optimised to a customer specified wavelength range. In many cases, the coating reduces reflection to below 0.5% per face or 1% total at the key wavelengths specified. Please advise the important wavelengths or wavelength range with your enquiry or order.


Wavelength ranges between 240 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 are also offered. Vac Techniche Kodial viewports are offered in CF, ISO and KF flange styles.
