Abstract
A high SAG optical lens and method for fast molding the same is disclosed, in which an optical lens is a single optical lens or an optical lens array formed by placing optical material between an upper mold and a lower mold for molding by heating and pressing processes; a formed rim is molded at the joint of the optical surface and the lens flange simultaneously. Therefore, it is convenient to fabricate the optical lens with high SAG and can eliminate the ghost phenomena effect occurring at the edge of the optical surface and the lens flange. Furthermore, since the feature of squeezing the melted optical material by the formed rim during the molding process, fast molding process can be successfully achieved.
