A casting method, rather than injection molding, to produce polymer optical components and systems is provided. The casting process controls shrinkage and stress, thus providing both high bulk uniformity and high quality, accurate surfaces, by incorporating polymer films into the mold. The films may remain incorporated into the part or may optionally be removed from the part after removal from the mold. In addition, the incorporation of separately produced components within the cast part is also provided, eliminating post-casting assembly manufacturing steps.
