Problems solved by technology

The current mainstream lenses on the market have the problem of small angle of view. For example, it is difficult to record the edge of the vehicle while the vehicle is driving. Moreover, similar lenses are large in size and low in resolution. The overall clarity of the image taken at night lower
That is, the existing lens cannot meet the requirements of large field of view, high definition and miniaturization at the same time

Abstract

The present invention provides an optical system, a lens module and an electronic device. The optical system includes sequentially from the object side to the image side along the optical axis: a first lens with negative refractive power; a second lens with positive refractive power, wherein the object side of the second lens is concave and the image side is convex; The third lens has a positive refractive power, the object side of the third lens is convex, and the image side is convex; the fourth lens has a negative refractive power, and the image side of the fourth lens is concave; the fifth lens has a positive refractive power, the object side of the fifth lens is convex, and the image side is convex; the optical system satisfies the conditional formula: -5<f12 / f345<-1, where f12 is the first lens and the first lens The composite focal length of the two lenses, f345 is the composite focal length of the third lens, the fourth lens and the fifth lens. The optical system of the present application simultaneously meets the requirements of a larger field of view, high definition and miniaturization.

Description

technical field [0001] The invention belongs to the technical field of optical imaging, and in particular relates to an optical system, a lens module and an electronic device. Background technique [0002] With the development of society, the requirements for safety and monitoring in various fields are getting higher and higher, especially in the field of transportation and vehicle monitoring. The mainstream lenses on the market now have the problem of small angle of view. For example, it is difficult to record the edge of the vehicle when the vehicle is driving, and the same type of lens is larger in size and lower in resolution. The overall clarity of the image taken at night lower. That is, the existing lens cannot meet the requirements of a larger field of view, high definition and miniaturization at the same time. SUMMARY OF THE INVENTION [0003] The purpose of this application is to provide an optical system, a lens module and an electronic device for solving the ...
