Optical processing turntable and projection device

The invention discloses an optical processing turntable and a projection device. The optical processing carousel has a first center of mass and a height. The optical processing turntable comprises a substrate and a driving assembly. The substrate has a second center of mass. The driving assembly is arranged on the base plate to drive the base plate to rotate. The driving assembly is provided with a locking face. And the distance between one of the first mass center and the second mass center, which is relatively far away from the locking surface, and the locking surface is less than or equal to 2/3 of the height. According to the invention, the vibration and noise of the optical processing turntable during high-speed operation can be effectively reduced, and the operation life of the optical processing turntable can be prolonged. 一种光学处理转盘以及投影装置。光学处理转盘具有第一质量中心及高度。光学处理转盘包括基板以及驱动组件。基板具有第二质量中心。驱动组件设置于基板上，以驱动基板旋转。驱动组件具有锁固面。第一质量中心与第二质量中心之中相对远离锁固面的一者与锁固面之间的距离小于等于2/3的高度。本发明可有效地减少光学处理转盘于高速运转时的振动与噪音，且可提升光学处理转盘的运转寿命。
