Wafer scale optics

A device comprising:

• a plurality of lenses, each lens having a contiguous portion that forms at least one alignment/attachment feature for that lens;
• a planar micro-electromechanical system (MEMS) structure having a complimentary alignment/attachment feature for each alignment/attachment feature of the plurality of lenses, wherein each complementary alignment/attachment feature of the planar MEMS structure is disposed perpendicular to the planar MEMS structure;
• wherein the alignment/attachment features of the plurality of lenses are disposed perpendicular to the planar MEMS structure and engage with the complimentary alignment/attachment features of the planar MEMS structure to align and attach the plurality of lenses to the planar MEMS structure;
• wherein the plurality of lenses comprises at least first and second lenses;
• wherein the alignment/attachment features of the at least first and second lenses each engages with the same complimentary alignment/attachment feature of the planar MEMS structure to align and attach the at least first and second lenses to opposing sides of the planar MEMS structure;
• wherein the planar MEMS structure is disposed in a plane that is perpendicular to a common optical axis of the at least first and second lenses;
• wherein the planar MEMS structure comprises silicon, an alloy, a metal, or a plastic;
• and
• wherein the alignment/attachment features of the at least first and second lenses each comprises a protrusion and at least one complimentary alignment/attachment feature of the planar MEMS structure comprises a cutout that is configured to receive the alignment/attachment features of the at least first and second lenses.

A method for aligning/attaching one or more lenses to one another and/or to a structure, the method comprising:

• attaching mating features of at least first and second lenses to complimentary mating features of a planar micro-electromechanical system (MEMS) structure,
• wherein the mating features of the at least first and second lenses are formed from contiguous portions of the at least first and second lenses,
• wherein the attaching comprises inserting the mating features of the at least first and second lenses into the complementary mating features of the planar MEMS structure by moving the at least first and second lenses toward opposing surfaces of the planar MEMS structure along a common optical axis of the at least first and second lenses;
• wherein the planar MEMS structure is disposed in a plane that is perpendicular to the common optical axis of the at least first and second lenses and the complimentary mating features are disposed perpendicular to the planar MEMS structure,
• wherein the mating features of the at least first and second lenses are each disposed perpendicular to the planar MEMS structure and each engages with the same complimentary features of the planar MEMS structure to align and attach the at least first and second lenses to opposing sides of the planar MEMS structure,
• wherein the planar MEMS structure comprises silicon, an alloy, a metal, or a plastic;
• and
• wherein the mating features of the at least first and second lenses each comprises a protrusion and at least one of the mating features of the planar MEMS structure comprises a cutout that is configured to receive the mating features of the at least first and second lenses.
