Abstract

The invention relates to an imaging lens, a lens comprising the same and electronic equipment. The imaging lens comprises a working part (11) and a supporting part (12) surrounding the working part (11), wherein a notch clearance surface (121) and a notch structure (122) located on the notch clearance surface (121) and bulges out of the notch clearance surface (121) are arranged in the side surface of the supporting part (12); a notch end surface (1221), away from one end of the notch clearance surface (121), of the notch structure (122) is formed by mutually connecting a cambered surface partand a plane part. The imaging lens effectively inhibits stray light of the notch end surface and improves the imaging quality.

Description

technical field [0001] The invention relates to the field of optics, in particular to an imaging lens, a lens including the imaging lens, and electronic equipment. Background technique [0002] In recent years, miniaturized lens modules have been increasingly used in electronic products such as mobile phones, tablet computers, and virtual reality. With the development of technology, the current lens modules not only put forward higher and higher requirements for imaging quality, but also have more and more stringent requirements for various types of stray light. Due to the increasing number of existing lens module lenses, and most of the imaging lenses are injection molded, the side edge of the non-effective diameter of the imaging lens has a high reflectivity, and it is difficult to reflect the reflection incident to this area. Light is effectively attenuated. Especially when there is a plane on the side, for example, the feed gate will form a smooth and straight shear pl...
