Description
The rugged construction of the Kodial viewports allows bake-out to 120 °C with UHV performance, whilst the window offers broadband optical transmission from the visible to near infra-red. Higher temperature specification non-magnetic viewports are available using fused silica and sapphire windows.
Anti-reflective coatings to match customer reflectance requirements are also processed at TSL. Please advise the wavelength or wavelength ranges of your application and a reflectance curve will be prepared. Non-standard viewports can be manufactured on request, including re-entrant style microscope/camera viewports. Annealed copper gaskets and other component accessories are also supplied by TSL.
