Abstract

The invention discloses an optical lens, a camera module and an electronic device. The optical lens comprises a first lens with positive refractive power sequentially arranged along an optical axis from an object side to an image side, the object side surface is convex, and the image side surface is concave; The second lens with negative power has a convex object side and a concave image side; the third lens with power has a convex object side; the fourth lens with power has a convex image side ; the fifth lens with negative refractive power; the sixth lens with positive refractive power; the seventh lens with negative refractive power, the object side is convex and the image side is concave. The optical lens also satisfies the relation: 7mm<f*tan(HFOV)<7.5mm. The optical lens, the camera module and the electronic device provided by the embodiments of the present invention can meet the design requirements of large image area, large wide angle and miniaturization of the optical lens.

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 pursuit of light, thin and miniaturized electronic products, the structural characteristics of ultra-thin and miniaturized optical lenses and the shooting effect of large image area and wide angle have gradually become the development trend of optical lenses. However, the five-piece optical lens and the six-piece optical lens used in the related art can no longer meet people's requirements for a large image area, wide angle, and ultra-thin miniaturization of the optical lens. At present, how to realize the design requirements of large image area, large wide angle, and ultra-thin miniaturization of optical lenses is still a technical problem that needs to be solved urgently in the field of optical imaging technology. SUMMARY OF THE INVENTION [0003] The embodiment of the i...
