Optical lens and imaging equipment

Abstract

The invention discloses an optical lens and an imaging device. The optical lens comprises in sequence from the object side to the imaging surface: a first lens with negative optical power, the object side is convex, and the image side is concave; degree of the second lens, its object side is convex, its image side is concave; the third lens with positive power, its object side and image side are convex; stop; the fourth lens with positive power, its The image side is convex; the fifth lens with negative power, its object side is concave, and its image side is convex at the near optical axis; the sixth lens with negative power, its object side is at the near optical axis It is convex and its image side is concave near the optical axis. The above-mentioned optical lens, through reasonable matching of six lens shapes and focal powers with specific refractive power, makes the field of view of the optical lens reach more than 150°, and the total optical length is less than 6mm, which better realizes large wide-angle, small size and The balance of high pixels can effectively improve the user's camera experience.

Description

technical field [0001] The invention relates to the technical field of lens imaging, in particular to an optical lens and an imaging device. Background technique [0002] At present, with the popularization of portable electronic devices (such as smartphones, tablets, and cameras), coupled with the popularity of social, video, and live broadcast software, people are more and more fond of photography, and camera lenses have become a must for electronic devices. Standard configuration, camera lenses have even become the primary consideration for consumers when purchasing electronic equipment. [0003] With the continuous development of mobile information technology, portable electronic devices such as mobile phones are also developing in the direction of ultra-wide-angle and ultra-high-definition imaging, which puts forward higher requirements for camera lenses mounted on portable electronic devices. However, in recent years, as consumers are keen on taking pictures with mobi...

Problems solved by technology

However, in recent years, as consumers are keen on taking pictures with mobile phones, the high pixel of the rear camera has reached its peak. When developing towards a higher pixel, it will encounter the mutual constraints of thinner and lighter mobile phones and the limitation of the total length of the camera. Therefore, the ultra-wide-angle or even fish-eye lens on the rear of the mobile phone may become a wave; then how to achieve the balance of large wide-angle, high pixel and small size of the camera lens has become an urgent problem to be solved
