Viewport Shutter Pneumatic, Swing Type, 100% Full Coverage, 96mm Aperture, CF152 ID / 203mm OD Flange

Some operations inside a vacuum system can cause harm or damage to a viewport. For example, Evaporation of metals in the UHV system can cause the viewport surface to become quickly coated, resulting in a mirror reflective surface. Removal and cleaning of the viewport will then be necessary before reusing it. To overcome these problems, we offer a range of viewport shutters, both Full-Coverage Swing Type and Venetian Blind Type (the latter being especially useful where a low profile when opened is preferable).
