Abstract

The invention relates to a wide-angle optical imaging lens which sequentially comprises a first lens, a diaphragm, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and an optical filter from an object side to an image side, and the wide-angle optical imaging lens meets the following relational expressions: TTL / f is less than or equal to 2.69; wherein TTL is the distance from the object side surface of the first lens to the image surface at the paraxial position, and f is the focal length of the imaging lens group. According to the wide-angle optical imaging lens, a six-piece type structure is adopted, and through matching of different refraction forces, the whole imaging lens has the good light convergence capacity, keeps the good wide-angle characteristic, has the good aberration correction capacity and meets the high-pixel requirement.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to a wide-angle optical imaging lens. Background technique [0002] With the rapid development of electronic technology, mobile and portable electronic devices have been rapidly popularized, such as smart phones, tablet computers, driving recorders and sports cameras, etc., which has also promoted the prosperity of related technologies of camera modules applied to electronic devices develop. With the improvement of semiconductor manufacturing process technology, the pixel size of the photosensitive device has been reduced, and the corresponding camera lens is gradually developing into the high-pixel field, and the requirements for its imaging quality are also increasing. [0003] In some specific scenarios, a device with a camera lens is also required to have a larger field of view. For example, in application scenarios such as front-facing selfies, game consoles, and panora...
