Problems solved by technology

[0002] At present, with the development of camera technology, optical lenses are more and more widely used in electronic devices such as smartphones, tablet computers, and video phones, such as taking pictures, taking pictures, or making video calls. The volume and imaging quality requirements of optical lenses are getting higher and higher. However, in related technologies, optical lenses cannot meet the design requirements of miniaturization and high imaging quality while having a long focal length.

Abstract

The invention discloses an optical lens, a camera module and an electronic device, 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 positive refractive power, the second lens has negative refractive power, the third lens has positive refractive power, the fourth lens has negative refractive power, and the sixth lens has positive refractive power. The fourth lens has negative refractive power, the fifth lens has positive refractive power, the sixth lens has negative refractive power, and the optical lens meets the following relational expressions: 45.5 < = f * 43 / ImgH < 61.0; wherein f is the effective focal length of the optical lens, and ImgH is the image height corresponding to the maximum field angle of the optical lens. According to the optical lens, the camera module and the electronic equipment provided by the invention, the optical lens has a long focal length, meanwhile, the miniaturization design requirement is met, and the imaging quality is improved.
