Abstract: A single-piece optical imaging lens and an array thereof are revealed. The optical imaging lens includes a lens and an image sensor arranged at an image-side surface of the lens. The lens includes an object-side surface, an image-side surface, an optical area, and a non-optical area. The optical imaging lens satisfies the following conditions: BFL/TTL=0.55˜0.81, OH/OD=1.0˜3.6. TTL is total length from the object-side surface of the lens on the optical axis to the image sensor. BFL is back focal length of the imaging lens. OD is the distance between an object on the optical axis and the object-side surface of the lens. OH is the largest height of an object vertical to the optical axis of OD. The single-piece optical imaging lens array is used to produce a plurality of single-piece optical imaging lenses by cutting.

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.
