Abstract

The invention discloses an optical imaging lens, comprising: the first lens has positive refractive power, and its image side is convex at the near optical axis; the second lens has negative refractive power, and the third lens has refractive power; the fourth lens has Refractive power, its object side is convex at the near optical axis, its image side is concave at the near optical axis; the fifth lens has refractive power; the sixth lens has refractive power, its object side is convex at the near optical axis, Its image side is concave at the near optical axis, and its image side has at least one inflection point; the seventh lens has refractive power; the eighth lens has refractive power, and its image side has at least one inflection point. The optical imaging lens of the present invention has short lens length, large aperture and excellent viewing angle, and can achieve good imaging quality, which can meet application requirements. The invention also provides an electronic device.

Description

technical field [0001] The invention relates to the technical field of optical systems, in particular to an optical imaging lens. The invention also relates to an electronic device. Background technique [0002] With the rapid development of electronic technology, mobile and portable electronic devices have been rapidly popularized, such as smart phones, tablet computers, driving recorders and sports cameras, etc., which has also promoted the prosperity of related technologies of camera modules applied to electronic devices develop. The camera modules of existing electronic equipment will be used to shoot distant scenes, and some will also be used to shoot people, close-ups, etc., which puts forward higher requirements on the imaging performance of imaging lenses such as resolution, aperture, and field of view. In addition, with the improvement of semiconductor manufacturing process technology, the pixel size of the photosensitive device has been reduced. Correspondingly, ...
