Abstract

The invention provides an optical lens, an imaging device and a terminal. The optical lens comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens which are sequentially arranged from the object side to the image side along the optical axis. The first lens with negative refractive power has an object-side surface and an image-side surface being concave ina paraxial region thereof. The second lens with positive refractive power has an object-side surface and an image-side surface being convex in a paraxial region. The fifth lens with positive refractive power has an image-side surface being convex in a paraxial region thereof. The sixth lens element with negative refractive power has an object-side surface being convex in a paraxial region and an image-side surface being concave in a paraxial region. The optical lens meets the relational expression: 60deg / mm<FOV / f<100deg / mm. The optical lens can achieve the effects of high image quality and wide angle.

Description

technical field [0001] The present application relates to the technical field of optical imaging, in particular to an optical lens, a camera module and a terminal. Background technique [0002] In recent years, with the advancement of the technology industry and the continuous development of imaging technology, optical lenses for optical imaging have been widely used in terminals such as smartphones, tablets, imaging, sensing, security, 3D recognition, and automation equipment. In recent years, there has been a development trend that a single terminal is equipped with multiple camera lenses with different functions at the same time. Especially in terms of wide-angle photography, the wide-angle is mostly an ordinary wide-angle less than 84 degrees. The size of the captured object space is very different from the viewing angle of the human eye, and the scenes included in daily use are limited. Therefore, a wide-angle lens with higher image quality is required to meet the deve...
