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 anda sixth lens which are sequentially arranged from an object side to an image side along an optical axis; the first lens has negative refractive power, the second lens has negative refractive power, and the third lens has positive refractive power. The fourth lens has positive refractive power, the fifth lens has negative refractive power, the sixth lens has positive refractive power, and the optical lens satisfies the following relation: 3.4 < (D34 + CT4) / (CT5 + D56) < 4. According to the optical lens, the camera shooting module, the electronic equipment and the automobile, due to the fact that the lens has the refraction power and the convex-concave design of the object side face and the image side face, when the relation that 3.4 < (D34 + CT4) / (CT5 + D56) < 4 is met, miniaturization design can be met, and meanwhile large-angle-range shooting and clear imaging can be achieved.

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, short and wide-angle optical lenses in various electronic devices, such as vehicle cameras and driving recorders. In the related art, under the design trend of miniaturization, the optical lens cannot meet the wide-angle shooting and clear imaging, so it cannot meet the demand of wide-angle shooting. Contents of the invention [0003] The embodiment of the invention discloses an optical lens, a camera module and its electronic equipment, and a car, which can realize shooting and clear imaging in a wide angle range while realizing the light, thin and miniaturize...
