Abstract

The invention discloses an optical lens, a camera module, an electronic device and a vehicle. The optical lens sequentially comprises a first lens with negative refractive power, a second lens with negative refractive power, a third lens with positive refractive power, a fourth lens with positive refractive power, a fifth lens with negative refractive power and a sixth lens with positive refractive power from an object side to an image side, wherein the object side surface of the fourth lens is a convex surface near an optical axis; the optical imaging system further comprises a diaphragm. Theoptical lens satisfies the following relational expression: 12.6 mm < 2 * f * tan(FOV / 2) <14.5 mm, f is the effective focal length of the optical lens, and FOV is the maximum field angle of the optical lens. The product of the effective focal length of the optical lens and the tangent value of half of the maximum field angle multiplied by 2 is between 12.6 mm and 14.5 mm, so that the distortion amount of the whole optical lens can be controlled, the distortion of the optical lens is small, the resolution capability of the optical lens is improved, the distortion risk of a picture shot at a large angle is reduced. And the imaging quality of the optical lens is improved.

Description

technical field [0001] The invention relates to optical imaging technology, in particular to an optical lens, a camera module, an electronic device and a vehicle. Background technique [0002] With the rapid development of economy and technology, automobiles have become a necessary means of transportation for every household. However, due to institutional constraints, automobiles have multiple visual blind spots. Since drivers cannot see these blind spots during driving, it is so easy to increase traffic accidents. risk of occurrence. [0003] Existing cars are generally equipped with a vehicle-mounted camera module. The vehicle-mounted camera module can capture the surrounding environment of the vehicle and transmit it to the display device, so that the user can obtain the environment around the vehicle more intuitively, so as to prevent traffic accidents caused by blind spots. Accidents happen. In order to increase the shooting range of the camera module, how to reduce t...
