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.
- Kodial 316LN DN150CF ViewportSKU: ZVPZL150£705.72A zero length viewport has a thickness no larger than that of its mounting flange. This makes it easier to protect from accidental damage. It provides the best angle of view as there are no tubulation walls to restrict observation. Kodial viewports are offered in CF flange styles. The viewports comprise borosilicate glass optic 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.
