KODIAL 304L VIEWPORTS
incl. VAT, plus shipping
Delivery Time 2 - 3 Weeks
A zero length viewport has a thickness no larger than that of its mounting flange. This makes it easier to protect from accidental damage. It provides the best angle of view as there are no tubulation walls to restrict observation. Kodial viewports are offered in CF flange styles. The viewports comprise borosilicate glass optic which is sealed to a Kovar weld ring using an induction heater process. The optic assemblies are helium leak tested and cleaned for ultra high vacuum (UHV) conditions.
Product DESCRIPTION
Kodial viewports are offered in CF flange styles. The viewports comprise a borosilicate glass optic which is sealed to a Kovar weld ring using an induction heater process. The optic assemblies are TIG welded in to flanges and are helium leak tested and cleaned for ultra-highvacuum (UHV) conditions. The CF versions are offered using 304L (or 316LN2D) stainless steel flanges. The rugged construction of the Kodial viewports allows repeated bake-out with UHV performance, whilst the window offers broadband optical transmission from the visible to near infra-red. Annealed copper gaskets are available.
