Torr Scientific manufactures over 3000 different viewports a year.
One of our core products is our standard range of Kodial viewports which are available in CF, ISO and KF 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 into flanges and are helium leak tested and cleaned for ultra-high vacuum (UHV) conditions. The CF versions are offered using 304L or 316LN stainless steel flanges. Flanges in 304L stainless steel are used for the high vacuum KF and ISO viewports. 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.
We also offer variations of these viewports with ITO (Indium Tin Oxide) coatings, Phosphor Screens, and lead glass disks for radiation protection.
