Kodial® Viewports

Zero length viewports provide a wide angle viewing window for your vacuum chamber. Manufactured using glass bonded sealing technology and completely adhesive free, they offer a stable platform for the addition of a viewport shutter, used to reduce the deposition on the window in vacuum coating systems.

Kodial viewports are offered in CF flange styles. The viewports comprise borosilicate glassoptic 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.
