  • Publication number: 20140112668
    Abstract: A stamped metal optic is provided that is a unitary, or integrally formed, part that includes at least a bench for holding at least one optoelectronic component and a reflector for folding an optical pathway. The stamped metal optic is formed of a piece of metal that is shaped using known metal stamping techniques. The stamped metal optic preferably has at least one fiducial mark formed therein that is used for placement of the optoelectronic device on the bench to ensure that the optoelectronic device is precisely aligned with the reflector. Because metal objects can be formed relatively inexpensively with high precision using known stamping techniques, the stamped metal optics can be manufactured with high precision at relatively low cost.
