Problems solved by technology

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 meet people's high-definition requirements of optical lenses. imaging requirements

Abstract

The invention discloses an optical lens, a camera module and electronic equipment. The optical lens comprises a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element and a sixth lens element which are sequentially arranged from an object side to an image side along an optical axis. The first lens element has positive refractive power and has a convex object-side surface; the second lens element has refractive power and has a convex image-side surface; the fourth lens element has a convex object-side surface and a concave image-side surface; the fifth lens element has a concave object-side surface and a convex image-side surface; and the sixth lens element has a convex object-side surface and a concave image-side surface. The optical lens satisfies the following relation: SDL1 / FNO is greater than 1mm and less than 1.7 mm, wherein SDL1 is the maximum effective aperture of the object side surface of the first lens element, and FNO is the aperture number of the optical lens. The optical lens, the camera module and the electronic equipment provided by the invention have the characteristics of large aperture and large image plane while being light, thin and miniaturized. The picture texture of the optical lens is improved, and the resolution and the imaging definition of the optical lens are 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...
