Method for encapsulating a microstructured lens by pipc

Abstract

A method of forming an optical lens includes providing a first mold insert of a molding device having a contacting surface, the contacting surface including a plurality of inverted microstructures disposed on the contacting surface, each microstructure of the plurality of inverted microstructures having a shape inversely related to a shape of microstructures on a surface of a molded base lens; replacing the first mold insert with a second mold insert having a contacting surface thereof; applying a curable coating to a surface of the base lens having the microstructures formed thereon; pressing the contacting surface of the second mold insert into at least a portion of the curable coating applied to the surface of the base lens; and curing the curable coating into a curable layer, the microstructures being substantially entirely encapsulated in the curable layer.
