Abstract

The invention provides an optical imaging lens. The optical imaging lens sequentially comprises a diaphragm and a first lens from the object side of the optical imaging lens to the image side of the optical imaging lens, wherein the first lens has positive focal power; the second lens is a liquid lens, the focal power of the second lens is continuously variable, and the object side surface of the second lens is a convex surface; a third lens, wherein the third lens has focal power; the fourth lens has negative focal power; a fifth lens, wherein the fifth lens has positive focal power; and the sixth lens has focal power. The optical imaging lens solves the problem that miniaturization and high image quality of an optical imaging lens in the prior art are difficult to consider at the same time.

Description

technical field [0001] The present invention relates to the technical field of optical imaging equipment, in particular to an optical imaging lens. Background technique [0002] With the continuous development of smartphone photography technology, camera modules have developed from single-camera, dual-camera to triple-camera, or even quadruple-camera. It has become a mainstream trend that at least one of the multi-camera lenses is an ultra-wide-angle lens. At the same time, with the development of mobile phones in the direction of thinner and lighter, it is necessary to design the optical imaging lens in the direction of miniaturization, which is easy to sacrifice the imaging quality of the optical imaging lens. [0003] That is to say, the optical imaging lens in the prior art has the problem of being difficult to balance miniaturization and high image quality. Contents of the invention [0004] The main purpose of the present invention is to provide an optical imaging ...
