ABSTRACT:
An exemplary method for making a lens array having many lenses includes the follow steps. A light pervious substrate including a supporting surface is firstly provided. Secondly, a molten molding material is applied on the supporting surface. Thirdly, a pressing mold including many molding parts is provided, each molding part including a molding cavity for molding the lens. Fourthly, the pressing mold is pressed on the molten molding material. Fifthly, the molten molding material is half-cured, thereby forming a half-cured molding material. Sixthly, the half-cured molding material is pressed by the pressing mold. Seventhly, the half-cured molding material is fully cured to form each lens in each molding cavity. Finally, the pressing mold is removed from the light pervious substrate to form the lens array.
