Abstract

The present application discloses an optical imaging lens, which sequentially includes from the object side to the image side along the optical axis: a first lens with refractive power, a second lens, a third lens, a fourth lens, a fifth lens, The sixth lens, the seventh lens and the eighth lens; the image side of the eighth lens is a convex surface; the distance TTL on the optical axis from the object side of the first lens to the imaging surface of the optical imaging lens is equal to the effective pixel area of ​​the optical imaging lens Half of the diagonal length ImgH satisfies: TTL / ImgH<1.2; and the effective focal length f8 of the eighth lens and the curvature radius R16 of the image side of the eighth lens satisfy: 0.5<f8 / R16<1.5.

Description

technical field [0001] The present application relates to the field of optical elements, in particular, to an optical imaging lens. Background technique [0002] With the rapid development of science and technology, portable electronic products such as smartphones, computers, and tablet computers are also gradually developing, and users have increasingly strict requirements on the imaging functions of portable electronic products such as smartphones. At the same time, in order to adapt to the miniaturization development trend of smart phones, the imaging lenses mounted on smart phones are also gradually becoming miniaturized, which makes the processing and assembly of the lenses more challenging. In addition, users have higher and higher requirements for the superior performance of smartphones such as ultra-wide-angle, telephoto, large aperture, and large image area. [0003] How to ensure the miniaturization of the lens, but also make the lens have a large image area and o...
