Abstract
Chalcogenide lens elements and methods of manufacturing such lens elements are provided. In one example, a method includes depositing a first chalcogenide layer on a substrate. The method further includes applying a first stamp to the first chalcogenide layer. The method further includes reflowing, in response to applying the first stamp, the first chalcogenide layer to form a first shaped chalcogenide layer. The method may further include singulating the substrate and the first shaped chalcogenide layer to obtain a plurality of chalcogenide lens elements.
Claims20
A method, comprising:
- depositing a first chalcogenide layer on a substrate;
- applying a first stamp to the first chalcogenide layer;
- and
- reflowing, in response to applying the first stamp, the first chalcogenide layer to form a first shaped chalcogenide layer;
- singulating the substrate and the first shaped chalcogenide layer to obtain a plurality of chalcogenide lens elements, wherein at least one of the plurality of chalcogenide lens elements has a length approximately between 0.5 mm and 15 mm, a width approximately between 0.5 mm and 15 mm, and a thickness approximately between 0.3 mm and 3.5 mm.
A chalcogenide lens element, comprising:
- a substrate comprising a first portion of a wafer-level lens array;
- and
- a first chalcogenide layer comprising a second portion of the wafer-level lens array,
- wherein the first chalcogenide layer is on the substrate, wherein the chalcogenide lens element has a length approximately between 0.5 mm and 15 mm, a width approximately between 0.5 mm and 15 mm, and a thickness approximately between 0.3 mm and 3.5 mm.
