Optical lens, camera module and electronic equipment

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, the first lens has positive refractive power, the second lens has negative refractive power, the third lens has negative refractive power, the fourth lens has refractive power, the fifth lens has positive refractive power, and the sixth lens has negative refractive power. The optical lens satisfies the following relations: 1.0 lt; tTL/(ImgH * 2) lt; 1.5, 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 long-focus characteristic can be met while the light, thin and miniaturized design is met, a good telephoto imaging effect is achieved, clear shooting of distant sceneries can be achieved, and high-definition imaging is achieved.

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...
