Problems solved by technology

In related technologies, an optical lens is often composed of multiple lenses. By increasing the number of lenses, the imaging resolution of the optical lens can be improved to achieve telephoto features. However, increasing the number of lenses will not only increase the cost of the optical lens, but also increase the cost of the optical lens. As a result, the weight and volume of optical lenses increase, which cannot meet the development trend requirements of thinness and miniaturization

Abstract

The invention discloses an optical lens, a camera module, an electronic device thereof and an automobile, 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 an object side to an image side along an optical axis, the first lens has refractive power, the second lens has positive refractive power, the third lens has positive refractive power, the fourth lens has negative refractive power, and the sixth lens has positive refractive power. The fourth lens has negative refractive power, the fifth lens has positive refractive power, the sixth lens has refractive power, and the optical lens satisfies the following relation: f * 43 / (2 * ImgH) > 62. According to the optical lens, the camera module, the electronic equipment and the automobile provided by the embodiment of the invention, the lens has the refractive power, the convex-concave design of the object side surface and the image side surface, and the relational expression of f * 43 / (2 * ImgH) > 62, so that the focal length of the optical lens can be controlled while the maximum image height range is met, the optical lens has a long focal length function, and the service life of the camera module is prolonged. Therefore, the imaging resolution of the optical lens is improved, and the imaging quality of the optical lens 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 and its electronic equipment, and an automobile. Background technique [0002] With the development of technology, the demand for the miniaturization of optical lenses and high-quality imaging quality is increasing day by day. It has become a development trend to use thin, light and compact optical lenses with excellent functions in various electronic devices, such as vehicle-mounted devices and driving recorders. In related technologies, an optical lens is often composed of multiple lenses. By increasing the number of lenses, the imaging resolution of the optical lens can be improved to achieve telephoto features. However, increasing the number of lenses will not only increase the cost of the optical lens, but also increase the cost of the optical lens. As a result, the weight and volume of the optical lens increase, which cannot meet th...
