Abstract
A system and method for rotary motion with vacuum sealing is provided. The system includes a vacuum chamber, a component mount disposed in the vacuum chamber, and a base. A bellows is disposed between the base and the component mount, and the bellows provides a seal between the base and the component mount. The bellows, the base, and the component mount define an actuator compartment therebetween. An actuator is disposed in the actuator compartment. The actuator is configured to rotate the component mount relative to the base in order to align a component disposed on the component mount. Rotation of the component mount relative to the base causes torsional elastic deformation of the bellows.
