Problems solved by technology

Although the fixed-focus design of the optical imaging lens can effectively realize the miniaturization of the lens, because it does not have zoom characteristics, it cannot meet the needs of imaging effects in different shooting scenarios, which limits the further development of mobile phone lenses in a wide range.

Abstract

The optical imaging lens sequentially comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens from an object side to an image side along an optical axis, an automatic focusing assembly; the second lens has focal power; the third lens has focal power; the fourth lens has focal power; and at least one subsequent lens having a focal power. At least one mirror surface from the object side surface of the first lens to the image side surface of the at least one subsequent lens is an aspheric mirror surface; the first lens is glued with the automatic focusing assembly; and the curvature radius of the image side surface of the automatic focusing assembly is variable.

Description

technical field [0001] The present application relates to the field of optical elements, and in particular, to an optical imaging lens. Background technique [0002] With the rapid development of portable electronic products such as smartphones, people have more and more diverse needs for photographing and photographing functions of smartphones in different scenarios. Based on the design concept of thin and light smartphones, the front optical imaging lens mounted on the smartphone often adopts a smaller fixed-focus system to better match the thin and light mobile phone. Although the fixed-focus design of the optical imaging lens can effectively realize the miniaturization of the lens, due to its lack of zoom characteristics, it cannot meet the needs of imaging effects in different shooting scenarios, which limits the further development of mobile phone lenses to a large extent. [0003] Therefore, how to design a miniaturized optical imaging lens with autofocus function to...
