Viewport Shutters These shutters are mounted behind a viewport to prevent build-up of deposition materials on viewports while in the closed position. They use a single plate shutter with a 90 degree opening rotation. Our design completely shields the viewing glass when the shutter is in the closed position. An integrated rotary motion feedthrough provides smooth actuation and a positive locking screw. Please cal for custom actuation options, such as motor drives or special flanges.
