Optical lens, camera module and electronic equipment

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 and a sixth lens which are sequentially arranged along an optical axis from an object side to an image side, the first lens has focal power, the object side surface and the image side surface of the first lens are concave and convex near the optical axis, the second lens has positive focal power, and the sixth lens has negative focal power. The third lens has positive focal power, and the object side surface and the image side surface of the third lens are concave surfaces and convex surfaces near the optical axis; the fourth lens has negative focal power, and the object side surface and the image side surface of the fourth lens are convex and concave near the optical axis; the fifth lens has positive focal power, and the object side surface and the image side surface of the fifth lens are concave and convex near the optical axis; the sixth lens has negative focal power, and the object-side surface and the image-side surface of the sixth lens are convex and concave near the optical axis. According to the optical lens, the camera module and the electronic equipment, a large-viewing-angle shooting effect can be realized on the basis of considering the miniaturization design requirement.

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] With the gradual popularization and upgrading of electronic devices (such as mobile phones, tablet computers, smart watches, etc.), the requirements for imaging quality and miniaturization design of camera modules are also getting higher and higher. At present, most of the high-pixel camera modules on the market often have a limited field of view and do not have a sufficient shooting range. And if you want a large viewing angle, since the large viewing angle requires the camera module to have a long overall length and a large volume, it is difficult to compress the size of the front end of the lens, which makes the camera module unable to achieve a miniaturized design and is difficult to adapt to miniaturized electronic devices. design requirements.

At present, most of the high-pixel camera modules on the market often have a limited field of view and do not have a sufficient shooting range.

And if you want a large viewing angle, since the large viewing angle requires the camera module to have a long overall length and a large volume, it is difficult to compress the size of the front end of the lens, which makes the camera module unable to achieve a miniaturized design and is difficult to adapt to miniaturized electronic devices. design requirements
