Summary:Systems and methods are disclosed for shaping and homogenizing a laser beam for interaction with a film. The shaping and homogenizing system may include a lens array and a lens that is positioned to receive laser light from the lens array and produce a respective elongated image in a plane for each lens in the lens array. In addition, the system may include a beam stop having an edge that is positioned in the plane, and a moveable mount rotating a lens of the lens array to vary an alignment between one of the elongated images and the beam stop edge.
