Problems solved by technology

However, with the introduction of thinner and lighter design requirements for smart phones, there are also requirements for the volume of the camera installed, and the size of the camera is also required to be miniaturized, which increases the difficulty of processing and molding the lenses of the camera. The imaging quality of the miniaturized camera poses a challenge

Abstract

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, a sixth lens, a seventh lens and an eighth lens which are sequentially arranged along an optical axis from an object side to an image side, the first lens has refractive power, the second lens has refractive power, the third lens has refractive power, the fourth lens has refractive power, the fifth lens has refractive power, the sixth lens has refractive power, and the eighth lens has refractive power. The fourth lens has positive refractive power, the object-side surface and the image-side surface of the fourth lens are convex surfaces near the optical axis, the fifth lens has negative refractive power, the sixth lens has refractive power, the seventh lens has refractive power, the eighth lens has refractive power, the object-side surface and the image-side surface of the eighth lens are convex surfaces and concave surfaces near the optical axis, and the optical lens meets the relational expression that Almax is less than or equal to 30deg. According to the optical lens, the camera module and the electronic equipment provided by the embodiment of the invention, the eight lenses are adopted, and the refractive power and the surface type of each lens are limited, so that the optical lens meets the design requirement of miniaturization, and the processing and forming difficulty of the lenses can be reduced.

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. Taking smart phones as an example, in order to improve the shooting effect, it has become the mainstream in the smart phone market to carry one, two or even three or more cameras with different orientation functions in the mobile phone. However, with the introduction of thinner and lighter design requirements for smart phones, there are also requirements for the volume of the camera installed, and the size of the camera is required to be miniaturized, which increases the difficulty of processing and molding the lenses of the camera. The imagi...
