Wafer level optical elements and applications thereof
Abstract:
A wafer level lens includes a first lens structure of a first polymeric material coupled to a second lens structure of a second polymeric material, wherein an interface is formed by opposing surfaces of the first lens structure and the second lens structure, the opposing surfaces having no air gap therebetween, at least one aperture disposed between the first lens structure and the second lens structure, wherein the aperture contacts the first lens structure and the second lens structure and wherein a supporting substrate is not positioned between the first lens structure and the second lens structure, and a spacer coupled to and separate from the wafer level lens.
