Zoom Lens, Camera Module, and Terminal Device - A simplified explanation of the abstract
This abstract first appeared for US patent application 17948335 titled 'Zoom Lens, Camera Module, and Terminal Device
Simplified Explanation
The abstract describes a zoom lens design that consists of four lens groups arranged along an optical axis. The first and third lens groups are fixed, while the second and fourth lens groups can move along the optical axis. The first lens in the first lens group is a biconvex lens, and there are at least two glass lenses in this group. The maximum clear aperture diameter of the zoom lens is between 4 mm and 12 mm.

Original Abstract Submitted
A zoom lens includes a first lens group, a second lens group, a third lens group, and a fourth lens group that are sequentially arranged from an object side to an image side along an optical axis. The first lens group and the third lens group are fastened, and the second lens group and the fourth lens group move along the optical axis. A first lens from the object side in the first lens group is a biconvex lens, and at least two lenses from the object side in the first lens group are glass lenses. A maximum clear aperture diameter of the zoom lens has the following relationship of 4 mm≤φ≤12 mm, where p is the maximum clear aperture diameter of the zoom lens.
