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.
You can choose to add a pneumatic actuator or stepper motor with or without position indicator.
