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.
