Abstract

The invention discloses an optical lens, a camera module, electronic equipment and an automobile. The optical lens comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens and an eighth lens which are sequentially arranged from an object side to an image side along an optical axis, wherein the first lens has negative refractive power; the second lens has negative refractive power; the third lens has positive refractive power; the fourth lens has negative refractive power; the fifth lens has positive refractive power, the sixth lens has positive refractive power, the seventh lens has negative refractive power, and the eighth lens has positive refractive power; the optical lens meets the following relation: -6 < f1 / f <-4, f1 is the focal length of the first lens, and f is the effective focal length of the optical lens. According to the optical lens, the camera module, the electronic equipment and the automobile provided by the invention, light rays emitted into the optical lens at a large angle can be grasped while the light, thin and small-sized design is met, the super-large-angle shooting requirement can be met, and high-pixel imaging can be realized.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to an optical lens, a camera module, electronic equipment and an automobile. Background technique [0002] At present, with the development of camera technology, people have higher and higher requirements for the imaging quality of optical lenses, and at the same time, the structural characteristics of lightness, thinness and miniaturization have gradually become the development trend of optical lenses. In related technologies, under the design trend of thin, light and miniaturized optical lenses, the shooting angle of the optical lens is small, the resolution is low, it is difficult to meet the shooting and clear imaging of a wide range of angles, and thus cannot meet the shooting requirements of a large field of view . Contents of the invention [0003] The embodiment of the invention discloses an optical lens, a camera module, an electronic device and a car, which can ...
