Abstract
Selective area stamping of optical elements may be performed to make multiple micro-optic components on one or two sides of a substrate may be fabricated using a batch process. The presence of molding material may be controlled on the substrate through the use of gaps.
Claims20
A method for making molded optical elements on selected areas on a surface of a substrate comprising:
- providing a first and second stamper each comprising a mold, said first and said second stamper being separated by a gap;
- coating said molds with a locally dispensed optically curable polymer;
- bringing said selected area on said surface of said substrate into contact with said coated molds;
- exposing said surface of said substrate in contact with said coated molds to light;
- and
- separating said substrate from said molds to leave said molded optical elements on said selected areas on said surface of said substrate.
