Abstract

An optical lens, camera module and electronic equipment, the optical lens includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens arranged in sequence along the optical axis from the object side to the image side , the refractive power of the first lens to the sixth lens is negative, positive, positive, positive, negative, positive in sequence, the image side of the fourth lens is convex at the near optical axis, and the object side of the fifth lens is at the near optical axis It is a concave surface, and the object side of the fifth lens is cemented with the image side of the fourth lens to form a cemented lens, and the optical lens satisfies: 3.0<f456 / f<4.2. By adopting the scheme of this embodiment, it is possible to reasonably control the power distribution of the fourth, fifth and sixth lenses. On the one hand, it is beneficial to control the incident light height of the light beam exiting the optical lens, so as to reduce the advanced aberration of the optical lens. and the outer diameter of the lens; on the other hand, it can correct the influence of the field curvature generated by the front lens group on the resolution, which is beneficial to improve the resolution and depth of field range of the optical lens, and improve the imaging effect.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to an optical lens, a camera module and an electronic device. Background technique [0002] With the development of the vehicle industry, the technical requirements for driving assistance cameras such as front view, side view, automatic cruise, driving recorder, and reversing image are getting higher and higher. The side-view camera is a vehicle-mounted camera used to monitor the road conditions on the left and right sides of the car. It enables the driver to intuitively identify and monitor the obstacles and pedestrians in the blind area on the left and right sides of the car while the car is driving. When turning or U-turning in places (such as intersections, roadblocks, parking lots, etc.), turn on the side-view camera at any time, make judgments on the driving environment, and feed back to the central system of the car to make correct instructions to avoid driving accide...
