optical lens

Abstract

The invention provides an optical lens, which comprises in sequence from the object side to the imaging surface: a first lens with negative refractive power, at the near optical axis, the object side and the image side are both concave surfaces; the first lens with positive refractive power Two lenses; diaphragm; the third lens with positive power, its image side is convex at the near optical axis; the fourth lens with positive power, at the near optical axis, its object side and image side are both a convex surface; a fifth lens with negative power; a sixth lens with negative power, the image side of which is concave at the near optical axis. Wherein, the FOV of the optical lens is >150°; the distance TTL from the object side to the image plane of the first lens of the optical lens is <5.8 mm.

Description

technical field [0001] The invention relates to the technical field of lens imaging, in particular to an optical lens. Background technique [0002] At present, with the improvement of the quality of life of the people, electronic consumer products are becoming more and more popular, and portable electronic devices (such as smart phones, tablet computers, etc.) naturally become consumers' primary considerations. With the rise of live streaming, social networking, and video software, consumers are paying more and more attention to the effects of taking pictures and taking pictures. Therefore, mobile phone camera lenses have become one of the primary considerations for consumers when purchasing electronic devices. [0003] With the continuous development of mobile information technology, portable electronic devices such as mobile phones are also developing in the direction of ultra-thin, ultra-high-definition imaging, and imaging diversification, which puts higher demands on t...

Problems solved by technology

In recent years, as consumers have become more and more fond of cameras, the requirements for camera lenses on portable electronic devices have also become higher and higher. While pursuing high-pixel, high-definition imaging, there are also improvements in imaging and imaging effects in different scenarios. Certain considerations; at the same time, under the trend of increasingly thinner and lighter portable electronic devices, there are also great requirements for the total length of the camera lens, and it is difficult for ordinary camera lenses to meet the requirements of consumers
