Abstract

An optical imaging lens includes, in order from an object side to an image side: a first lens element with positive refractive power having a convex object-side surface in a paraxial region thereof; a second lens element with negative refractive power having an object-side surface being concave in a paraxial region thereof; a third lens element with positive refractive power having an object-side surface being concave in a paraxial region thereof and an image-side surface being convex in a paraxial region thereof; and a fourth lens element with negative refractive power having an object-side surface being convex in a paraxial region and being concave in an off-axis region, and an image-side surface being concave in a paraxial region and being convex in an off-axis region. When specific conditions are met, the optical imaging lens can meet the requirements of miniaturization and wide viewing angle at the same time.

Description

technical field [0001] The invention relates to a lens, in particular to an optical imaging lens with four lenses. Background technique [0002] With the improvement of semiconductor process technology, the performance of electronic photosensitive elements has been improved, and the pixel size can reach a smaller size. Therefore, optical lenses with high imaging quality have become an indispensable part. [0003] Moreover, with the advancement of technology, optical imaging lenses can be applied to electronic devices in more fields, and the requirements for optical imaging lenses are also more diverse. Since the existing optical imaging lens is not easy to achieve a balance among requirements such as imaging quality, sensitivity, aperture size, volume or viewing angle, the present invention provides an optical imaging lens to meet the requirements. Contents of the invention [0004] Therefore, the main purpose of the present invention is to provide an optical imaging lens...
