Viewports
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 304L DN38CF ViewportSKU: ZVPZ38£76.28A 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. -
Kodial 304L DN16CF ViewportSKU: ZVPZ16£73.82A 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. -
Viewport ShutterSKU: ZVPSAvailable Soon£0.00Viewport shutters are used to protect the internal surface of a viewport from build-up of deposition material ejected during thin film processing of substrates. The shutter design is built to allow the widest possible viewing angle, and the maximum level of protection of the viewing area. -
Lead Glass DisksSKU: VPZ LGDRAvailable Soon£0.00Lead Glass Disks are used in applications where there is a risk of X-ray exposure through an unshielded viewport. The Lead Glass disks can be attached to the air side face of any UHV viewports via a fixing ring which is bolted directly to the viewport. -
Calcium Fluoride Zero Length ViewportSKU: ZVPCFAvailable Soon£0.00Calcium fluoride viewports are offered in CF flange styles. The UHV CF versions are offered using 304L stainless steel flanges. -
Fused Silica Quartz ViewportSKU: ZVPFSQAvailable Soon£0.00A zero length viewport has a thickness no larger than that of its mounting flange. It provides a wide angle viewing window for your vacuum chamber as there are no tubulation walls to restrict observation. Manufactured using high purity fused silica quartz. -
Sapphire ViewportSKU: ZVPSAAvailable Soon£0.00A zero length viewport has a thickness no larger than that of its mounting flange. It provides a wide angle viewing window for your vacuum chamber as there are no tubulation walls to restrict observation. Manufactured using Sapphire, these viewports are used in high temperature high transmission applications.
