Problems solved by technology

At present, when the optical lens is designed in a small size, the assembly of the structure of the optical lens is the primary consideration. This is because, in order to meet the miniaturization design, the production and manufacture of the components of the optical lens are more difficult, which also leads to an increase in the difficulty of assembly. In turn, the overall manufacturing cost of the optical lens is higher, which is not conducive to the control

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 and a fifth lens which are sequentially arranged from an object side to an image side along an optical axis; wherein the first lens has positive focal power, the second lens has negative focal power, the third lens has focal power, the fourth lens has positive focal power, the fifth lens has negative focal power, and the optical lens meets the following relational expression: 3.5 < f34 / (CT3 + CT4) < 15. According to the optical lens, the camera module and the electronic equipment provided by the embodiment of the invention, when the optical lens meets the relational expression that f34 / (CT3 + CT4) is more than 3.5 and less than 15, the aberration correction of the front lens group of the optical lens can be effectively realized, and the improvement of the assembly yield of the optical lens is also facilitated. Besides, the optical lens can realize the miniaturization and light and thin design of the optical lens through the distribution of the surface types and the refractive power of the lenses, thereby reducing the structural assembly difficulty of the optical lens, and facilitating the control of the production and manufacturing cost 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 electronic equipment. Background technique [0002] In recent years, with the advancement of the technology industry, imaging technology has continued to develop, and optical lenses for optical imaging have been widely used in electronic devices such as smartphones, tablet computers, and cameras. In order to meet the thin and light design requirements of electronic equipment, the miniaturization design of optical lenses also poses challenges. At present, when the optical lens is designed in a small size, the assembly of the structure of the optical lens is the primary consideration. This is because, in order to meet the miniaturization design, the production and manufacture of the components of the optical lens are more difficult, which also leads to an increase in the difficulty of assembly. Furthermore, the overall manufacturing cos...
