VacTechniche Vacuum Optics – Viewports

Kodial Zero Length Viewports

VacTechniche Kodial viewports are offered 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 in to anges and are helium leak tested and cleaned for ultra high vacuum (UHV) conditions. The CF versions are offered using 304L or 316LN stainless steel anges. Flanges in 316L stainless steel are used for the high vacuum KF and ISO viewports.
