Abstract

The invention provides an optical imaging system, an image capturing module, an electronic device and an automobile. The optical imaging system includes, in order from an object side to an image side:a first lens having negative refractive power; a second lens having positive refractive power, wherein the object side surface and the image side surface of the second lens are convex surfaces; a third lens having negative refractive power, wherein the object side surface and the image side surface of the third lens are concave surfaces; a fourth lens element having negative refractive power, wherein the object side surface and the image side surface of the fourth lens are concave surfaces; a fifth lens element having positive refractive power, wherein the image side surface of the fifth lensis a concave surface; a sixth lens element having positive refractive power, wherein the object side surface of the sixth lens is a convex surface; and a seventh lens having negative refractive power, wherein the object side surface of the seventh lens is a concave surface. The optical imaging system can capture an object in a long distance, and the imaging quality is high; all the lenses are tightly arranged so that the head of the optical imaging system is small in caliber, long in depth and short in total length, and the characteristic of miniaturization is achieved.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to an optical imaging system, an imaging module, an electronic device and an automobile. Background technique [0002] With the continuous development of automotive safety technologies such as assisted driving technology, automatic driving technology and unmanned driving technology, the application of vehicle cameras is also becoming more and more extensive. The installation positions of vehicle lenses are different, and their functions are also different. Among them, the front-view camera It can obtain images of blind spot areas outside the observation area of ​​the human eye to provide reference for people, so that the driver can grasp the road conditions ahead in real time during driving, and provide guarantee for safe driving. Therefore, the front-view camera should be used while ensuring high-pixel imaging. Longer focal length. [0003] In the process of implementing t...
