Viewport Shutter, Swing Type, 100% Full Coverage, 67mm Aperture, CF100 ID / 152mm OD Flange
SKU: VPS100ST
Some operations in the vacuum system may cause damage to the window. For example, metal evaporation in ultra-high vacuum systems can cause the surface of the window to be coated, making the inner surface of the window a reflective mirror. This results in the need to remove the window and clean the surface before reuse.

To overcome this problem, we provide a series of window baffles.

We provide lamella shutter and shutter shutters to choose from. Shutter shutters are aimed at large observation ports. The advantage is that the shutter opening movement traces are smooth and the amplitude is small.

Viewport Shutter Pneumatic, Swing Type, 100% Full Coverage, 96mm Aperture, CF152 ID / 203mm OD Flange
SKU: VPS150ST
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).
