Abstract
A holder/optical-element assembly includes a holder and an optical element disposed within the holder. The holder has an inner periphery surface in which at least one opening is provided, and the optical element is formed with at least one protrusion extending outward from an outer periphery of the optical element. The protrusion of the optical element is engaged with the opening of the holder.
Claims22
An assembly comprising an optical element disposed within a holder,
- wherein the holder has an inner periphery surface having a plurality of micro-pores that have a size ranging from a few microns to approximately 100 μm and are continuous, and the optical element has a plurality of protrusions extending outward from a periphery of the optical element, at least one of the plurality of protrusions being engaged with at least one of the plurality of micro-pores but not filling the plurality of micro-pores.
A method for manufacturing an assembly, the method comprises:
- providing a holder having a plurality of micro-pores, which have a size ranging from a few microns to 100 μm and are continuous 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 at least one of the plurality of micro-pores but not filling the plurality of micro-pores.
An assembly comprising an optical element disposed within a holder,
- wherein the holder comprises a plurality of micro-pores, which have a size ranging from a few microns to 100 μm and are continuous along an inner periphery surface, disposed over an inner periphery surface of the holder, and a protrusion of the optical element engages at least one of the plurality of micro-pores.
A method for manufacturing an assembly, the method comprising:
- providing a holder having a plurality of micro-pores, which have a size ranging from a few microns to 100 μm and are continuous along an inner periphery surface;
- placing a volume of an optical-element material within the holder, the volume being in excess of a volume required for forming the optical element;
- and
- pressing the optical-element material to integrate the optical element with the holder.
