In this whitepaper, we introduce a novel optical replication manufacturing method. We investigate the manufacture and measurement of freeform optics, explain how this high-precision replication manufacturing method works, and outline the benefits this manufacturing solution brings to OEMs and any organisation who wants to benefit from the inclusion of freeform optics at cost and at scale across their imaging applications.
