Abstract
The invention provides a projection system and a light-homogenizing device adjustment element for adjusting the position of a light-homogenizing device. The light-homogenizing device adjustment element has an actuator, and the actuator leans against one side of the light-homogenizing device and has a plurality of curved surfaces with different radii of curvature. When the actuator rotates, different curved surfaces push the light-homogenizing device to cause the light-homogenizing device to move in at least one direction from an initial position.
