Patent ID: 8070991

Claim:
A method for making a lens array having a plurality of lenses, comprising: providing a light pervious substrate, the light pervious substrate comprising a supporting surface; applying a molten molding material on the supporting surface; providing a pressing mold, the pressing mold comprising a plurality of spaced molding parts, each molding part comprising a molding cavity for molding an optically active portion of each lens; pressing the pressing mold on the molten molding material with a first pressure, for molding the molten molding material in the molding cavities; half-curing the molten molding material at a first temperature, thereby forming a half-cured molding material between the pressing mold and the light pervious substrate; pressing the pressing mold on the half-cured molding material with a second pressure; fully curing the half-cured molding material at a second temperature to form the lenses in molding cavities, the second temperature being higher than the first temperature; and removing the pressing mold from the light pervious substrate to form the lens array, the lens array comprising the light pervious substrate and the lenses.
