Abstract:
An optical element includes an optical lens produced by an additive manufacturing method and a holder formed at least in part with the optical lens by the additive manufacturing method. The holder is adapted for cooperation with a manufacturing machine to thereby position the optical lens at a predetermined position in the manufacturing machine. A corresponding assembly and a method of manufacturing an optical element are also described.
