Ultra High Vacuum Viewports

Vacuum viewports are fabricated in viewing diameters from 16mm to 14Omm. These are made from optical quality 'Corning 7056′ glass sealed into 'Kovar' spinnings which are then welded into vacuum flanges. Viewports can be supplied in 'Conflat' and ISO KF or LF flanges. Special viewports with different window materials, e.g. magnesium flouride or quartz, viewports with lead glass, viewports with anti-reflex coating can be supplied as can non standard vacuum flange configurations.
