Abstract

The invention discloses an optical lens, a camera module and electronic equipment. 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 from an object side to an image side along an optical axis; the first lens has negative refractive power, the object side surface and the image side surface of the first lens are respectively a convex surface and a concave surface, the second lens has positive refractive power, the object side surface of the second lens is a convex surface, the sixth lens has negative refractive power, the object side surface and the image side surface of the sixth lens are respectively a convex surface and a concave surface, and the optical lens meets the following relation: (FNO * TTL) / IMGH is more than 3 and less than 4, FNO is the number of apertures of the optical lens, TTL is the distance from the object side surface of the first lens to the imaging surface of the optical lens on the optical axis, and IMGH is the radius of the maximum effective imaging circle on the imaging surface of the optical lens. According to the optical lens, the camera module and the electronic equipment provided by the invention, the drawing texture of the optical lens can be improved, and the resolution ratio and the imaging definition of the optical lens can be improved while the light, thin and miniaturized design is met, so that the shooting quality of the optical lens is improved.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to an optical lens, a camera module and electronic equipment. Background technique [0002] At present, with the development of camera technology, people have higher and higher requirements for the imaging quality of optical lenses, which not only requires optical lenses to be thinner, lighter and smaller, but also to achieve higher imaging quality. In order to achieve higher imaging quality, optical lenses need to increase the number of lenses to correct aberrations. However, the increase in the number of lenses increases the difficulty of processing and assembling the lenses, and increases the volume of the optical lens. Therefore, in the related art, under the design trend of thin, light and miniaturized optical lenses, the image quality of optical lenses is poor, the resolution is low, and the imaging quality of optical lenses is not clear enough, it is difficult to mee...
