Original Abstract Submitted
A rotational lens assembly reduces the size of a gap between a lens and a frame of an optical light engine projector assembly. The lens includes a thread structure arranged around the outside edge of the lens. The thread structure allows the lens to align and lock within the optical assembly via at least a partial rotation of the lens. In addition, the rotation of the lens during assembly results in a relatively small gap between the lens and the frame. The smaller gap, in turn allows the other components of the optical assembly to be manufactured with lower tolerances for variation, improving the overall performance of the optical assembly.
