Viewport Shutter, Venetian Type, 67mm Aperture, CF152 Flange

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.
