High-resolution movable phone lens optical system

Abstract

The invention relates to a high-resolution movable phone lens optical system, which comprises a diaphragm, a crescent-shaped first lens with positive focal power, a crescent-shaped second lens with negative focal power, a crescent-shaped third lens with positive focal power, a fourth lens with negative focal power and an optical filter which are sequentially arranged along an incident light path from front to back, front and rear lens surfaces of the first lens, the second lens, the third lens and the fourth lens all adopt extended odd aspheric surfaces, and the surface equation of the aspheric surfaces is shown in the specification, wherein the conic coefficient is a quadric surface conic coefficient; wherein the number is the term number of the power series sum; wherein the coordinates are radial light coordinates; wherein the coordinates are standardized radial coordinates; wherein the coefficient is the coefficient of the second power. The high-resolution movable phone lens opticalsystem has the advantages of being simple in structure, large in field angle, large in receiving aperture, high in imaging quality, loose in tolerance, convenient to machine, install and adjust and the like.

Description

technical field [0001] The invention relates to a high-resolution mobile phone lens optical system, which belongs to the technical field of imaging lens system design. Background technique [0002] Because mobile phones have brought a lot of convenience to people's lives, they have become an indispensable part of people's lives; in addition, with the continuous introduction of high-end mobile phones, the camera function of mobile phones is an important measurement target for measuring the quality of high-end mobile phones.
