VACGEN offer a complete range of UHV compatible viewports to suit all clean and UHV applications. They have a wide angle of vision, maximum protection from accidental damage and minimum transmission of strain from flange bolts.
The standard range of Kodial® viewports covers the visible spectrum. Sapphire and Quartz versions cover the ultra-violet and infra-red regions respectively. Zero length viewports do not protrude beyond the mounting flange making them less prone to accidental damage.
