Optical imaging lens

Abstract

The invention discloses an optical imaging lens. The optical imaging lens sequentially comprises first, second, third, fourth, fifth and sixth lenses arranged from an object side to an image side, wherein a vignetting stop is arranged between the object side surface of the third lens and the image side surface of the fourth lens; for the optical imaging lens, conditions that Fno is not greater than 2 and TTL / IS is not greater than 1 are satisfied. Or the optical imaging lens sequentially comprises first, second, third, fourth and fifth lenses arranged from an object side to an image side, wherein a vignetting stop is arranged between the object side surface of the third lens and the image side surface of the fourth lens; for the optical imaging lens, conditions that Fno is not greater than 2 and TTL / IS is not greater than 1 are satisfied. The optical imaging lens is used for realizing optical shooting imaging, through forming the vignetting stop and designing optical parameters at least satisfying two conditions, and better optical performance, relatively short effective focal length and relatively large visual angle are realized when integral length of the optical imaging lens is shortened.

Description

technical field [0001] The invention relates to an optical imaging lens. Background technique [0002] Due to the advancement of technology, consumers' demand for small electronic products continues to increase. The characteristics applied to the optical imaging lens, the key components of the optical imaging lens combined in consumer electronic products should keep pace with the development of technology to meet the expectations of consumers. Some important characteristics of optical imaging lenses include image quality and size. Under the condition of miniaturized products, the improvement of image sensor technology plays an important role in maintaining (or improving) consumers' expectations for image quality. However, reducing the size of the imaging lens while maintaining good optical properties will encounter great challenges. For example, the distance along the optical axis from the object side of the first lens to the imaging surface of five-element and six-elemen...

However, it will be a great challenge to reduce the size of the imaging lens while maintaining good optical characteristics

For example, the distance along the optical axis from the object side of the first lens to the imaging surface of five-element and six-element optical imaging lenses is generally too long, so they cannot match the size of current mobile phones or digital cameras To concentrate the light on the image plane

[0003] In the past inventions, in terms of five-element or six-element lens structure, when the length of the lens is shortened to a certain extent, the light with a large angle cannot be effectively focused on the imaging surface, resulting in a decrease in image quality

[0004] Under the condition of maintaining good optical performance, the size of the optical lens should be reduced at the same time, which cannot be achieved only by reducing the number of lenses
