Claims16
Membrane suspended optical elements, comprising:
- a substrate including a plurality of apertures therethrough;
- and
- an array of membranes and first optical elements, wherein
- each of the membranes is formed with one of the first optical elements from flowable material that is subsequently cured such that each of the first optical elements is surrounded and suspended by membrane within one of the apertures,
- the flowable material forms a cured flowable material after it is subsequently cured, and
- each of the apertures comprises an overflow region adjacent to an inner surface thereof, and the membranes and first optical elements are integrally formed with a portion of the cured flowable material in the overflow region.
