Description
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 the 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. The rugged construction of the Kodial viewports allows repeated bake-out with UHV performance. The kodial/lead glass window assembly provides visible transmission as shown in the graph below.
