A holder/optical-element assembly comprising an optical element disposed within a holder,
- wherein the holder has an inner periphery surface in which at least one opening is provided, and the optical element has at least one protrusion extending outward from a periphery of the optical element, the at least one protrusion being engaged with the at least one opening.
A method for manufacturing a holder/optical-element assembly, the method comprises:
- providing a holder having at least one opening along an inner periphery surface;
- placing a volume of an optical-element material within the holder, the volume exceeding a minimum volume required for forming the optical element;
- and
- pressing the optical-element material to integrate the optical element with the holder,
- wherein an excess volume from the pressed optical-element material creates at least one protrusion, the at least one protrusion being engaged with the at least one opening.
