Vacuum Viewports – Extended Range Optics Ultra High Vacuum Viewports

These ultra-high vacuum (UHV) viewports use materials for windows such as Zinc Selenide, Magnesium Fluoride and Calcium Fluoride. We offer metal sealed (CF Flange)  extended-range optics in 1 inch and 2 inch view diameters with a combined range of transmission from 120nm to 20 microns. Coatings which enhance the transmission performance of many of these viewports are offered as standard options.
