  • Patent number: 7473091
    Abstract: Disclosed herein is an apparatus for manufacturing a megapixel multi-focus lens. The lens manufacturing apparatus of the present invention includes a loading means for supplying a mold body, in which a blank, interposed between upper and lower molds, is placed, to a forming position, a compression-forming means, which preheats, compresses and cools the supplied mold body such that the blank is formed into a multi-focus lens having an aspherical surface, and a discharge means, which discharges the multi-focus lens formed by the compression-forming means. Therefore, processes from loading to discharging can be automated, so that the productivity of the apparatus for manufacturing the multi-focus lens can be markedly enhanced. Furthermore, because the lens manufacturing apparatus is covered with a cabinet, a superior appearance thereof is ensured.
