Abstract
An optical processing turntable and a projection device are provided. The optical processing turntable has a first mass center and a height. The optical processing turntable includes a substrate and a driving component. The substrate has a second mass center. The driving component is disposed on the substrate to drive the substrate to rotate. The driving component has a locking surface. A distance between the locking surface and one of the first mass center and the second mass center relatively far from the locking surface is less than or equal to ⅔ of the height. The invention can effectively reduce the vibration and noise of the optical processing turntable during high-speed operation, and can increase the operating life of the optical processing turntable.
