Abstract

The invention discloses an optical lens, a camera module, an electronic device and an automobile, the optical lens comprises a first lens with negative refractive power which is sequentially arranged from an object side to an image side along an optical axis, and the object side surface and the image side surface of the first lens are respectively a convex surface and a concave surface; a second lens element with negative refractive power having a concave image-side surface; the third lens element with positive refractive power has a convex object-side surface and a convex image-side surface. The fourth lens element with positive refractive power has a convex object-side surface and a convex image-side surface. The fifth lens element with negative refractive power has a concave object-side surface and a convex image-side surface, respectively. The sixth lens element with positive refractive power has a convex object-side surface and a convex image-side surface. The optical lens meets the requirement of 3mm lt; f * tan (FOV / 2) lt; 4 mm. According to the optical lens, the camera module, the electronic equipment and the automobile provided by the invention, the miniaturization of the optical lens can be realized, the characteristics of large aperture and wide angle can be realized, and the imaging definition is improved.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to an optical lens, a camera module, an electronic device and an automobile. Background technique [0002] With the increasing demand for camera functions in smart phones, automobiles, monitoring equipment, medical equipment and other equipment, the application of camera modules is becoming more and more extensive. The shooting angle and imaging quality requirements of the optical lenses in the group are getting higher and higher. However, in the actual design, in order to achieve the large aperture and wide angle of the optical lens, the size of the optical lens will be large, the internal structure of the above equipment is relatively complex, the installation space of the camera module is small, and the large-sized optical lens It will increase the installation difficulty of the camera module, and cannot realize the universality of the camera module.
