Abstract

The invention provides an optical imaging system, an image capturing module and an electronic device. The optical image imaging system includes, in order from an object side to an image side: a firstlens with positive refractive power, the object-side surface of the first lens being convex at an optical axis; a second lens with refractive power; a third lens with refractive power; a fourth lens with positive refractive power, the image-side surface of the fourth lens being convex at the optical axis; a fifth lens with refractive power; a sixth lens with refractive power, the object-side surface of the sixth lens being a convex surface at the optical axis, and the image-side surface of the sixth lens being a concave surface at the optical axis; the optical imaging system satisfies the following conditions: 0.5 < f1/f26 < 1.6, wherein f26 is the combined focal length of the second lens, the third lens, the fourth lens, the fifth lens and the sixth lens, and f1 is the effective focal length of the first lens. The optical imaging system has the advantages of wide viewing angle and head miniaturization.

Description

technical field [0001] The invention relates to optical imaging technology, in particular to an optical imaging system, an imaging module and an electronic device. Background technique [0002] In recent years, full-screen mobile phones have gradually been favored by consumers. It can be seen that high screen-to-body ratio has become a development trend of mobile phones. Under this trend, the size of mobile phone camera lenses is required to be miniaturized, while ensuring high imaging Quality, so the specification requirements for camera lenses are getting higher and higher. [0003] In the process of implementing this application, the inventors found that there are at least the following problems in the prior art: Although the traditional camera lenses mounted on portable electronic products can meet the miniaturization requirements, the head of the camera lens is relatively large, which is not conducive to taking pictures. The lens is packaged under the screen, and the s...
