A stacked disk-shaped optical lens array, a stacked disk-shaped lens module array and a method of manufacturing the same are revealed. The stacked disk-shaped optical lens array is produced by stacked disk-shaped optical lens modules whose optical axis is aligned. The stacked disk-shaped lens module array is produced by a stacked disk-shaped optical lens array whose optical axis is aligned by an alignment fixture, stacked and assembled with required optical element arrays. In the stacked disk-shaped lens module array produced by this method, the lens optical axis is aligned precisely. Moreover, the manufacturing process is simplified and the cost is reduced.

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.

A lens holder for alignment of a stacked lens module and a manufacturing method thereof are revealed. A stacked lens submodule disposed with at least one first alignment fixture is used as a molding insert to be set into a mold arranged with a second alignment fixture where the first alignment fixture connects with the second alignment fixture correspondingly. Then by injection or press molding of the embedded molding insert, a lens module with the lens holder for alignment is formed. Thereby the conventional manufacturing method of the lens molder is improved, the processes are simplified and the yield rate is increased. Moreover, the molded lens module is packed into the lens more easily so that it is suitable to be applied to camera lenses, small lenses and mobile phone lenses.

A lens holder of a stacked lens module and a manufacturing method thereof are revealed. A stacked lens submodule is used as a molded molding insert to be set into a mold cavity. The molding insert is aligned in the alignment fixture and the clamp of the mold by injection molding or press molding. After molding process, a lens module included the stacked lens submodule as well as the lens holder is formed. Thereby the manufacturing method of conventional lens assemblies or lens modules is improved. Moreover, the processes are simplified and the yield rate is increased. Furthermore, the molded lens module is packed into the lens more easily so that it is suitable to be applied to camera lenses, small lenses and mobile phone lenses.
