Abstract

The invention discloses an optical lens, a camera module, an electronic device 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 along an optical axis from an object side to an image side. The first lens has positive refractive power, the object side surface and the image side surface of the first lens are a convex surface and a concave surface near the optical axis respectively. The second lens has negative refractive power, and an object-side surface and an image-side surface thereof are concave in a paraxial region. The third lens has positive refractive power, and an image-side surface thereof is convex in a paraxial region. The fourth lens has negative refractive power, and has a convex object-side surface and a concave image-side surface in paraxial regions, respectively. The fifth lens has positive refractive power, and an object-side surface and an image-side surface thereof are convex in a paraxial region. The sixth lens has refractive power, and has a convex object-side surface and a concave image-side surface in paraxial regions, respectively. According to the optical lens, the characteristics of small distortion and large aperture of the optical lens can be achieved, and the imaging quality requirement of the optical lens is effectively met.

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] With the development of the vehicle industry, the country’s requirements for road traffic safety and vehicle safety continue to increase, and the technical requirements for vehicle cameras such as ADAS (Advanced Driving Assistance System), driving recorder, and reversing images are getting higher and higher. . Not only requires good imaging quality, but also higher and higher requirements for distortion. However, most of the current vehicle lenses have disadvantages such as large distortion, insufficient aperture, and large head diameter, which cannot meet the imaging quality requirements of vehicle lenses. Contents of the invention [0003] The embodiment of the invention discloses an optical lens, a camera module, electronic equipment and a car, which can effectiv...
