Abstract
A system in process for producing an improved plastic molded optical element such as a mirror or lens is provided. The molded optical body has at least a surface portion designed for effective interfacing with incident light by reflection or refraction. Discontinuities form reference points at fixed positions on the molded optical surface. The reference points can include a projection or recess formed at the center of the lens system on the optical axis having a sufficient magnitude in size for measurement to determine a spatial position of the optical element but limited in size to prevent any perceptible aberration to be introduced within the desired application of the optical element.
