Wide-angle optical lens applied to high-resolution mobile phone and ultra-thin high-image-quality camera

Abstract

The invention relates to a wide-angle optical lens applied to a high-resolution mobile phone and an ultra-thin high-image-quality camera. The wide-angle optical lens comprises a lens cone, wherein a diaphragm is arranged at the front end of the lens cone; in a cavity of the lens cone, the diaphragm is provided with a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens from exterior to interior; the first lens is a positive focal distance lens, the first object plane, towards an object plane, of the first lens is a hyperbolic-type aspherical surface, and the first image plane, towards an image plane, of the first lens is a circular aspherical surface. The two surfaces of the second lens are negative focal distance lens bodies in the shape of a crescent, and the two surfaces of the second lens are both hyperbolic-type aspherical surfaces; the third lens is a positive focal distance lens, the second object plane, towards the object plane, of the third lens is a hyperbolic-type aspherical surface, and the second image plane, towards the image plane, of the third lens is an oblate aspherical surface; the fourth lens is a positive focal distance lens, and the two surfaces of the fourth lens are both hyperbolic-type aspherical surfaces; the fifth lens is a negative focal distance lens, and the two surfaces of the fifth lens are both hyperbolic-type aspherical surfaces; the sixth lens is a positive focal distance lens, and the two surfaces of the sixth lens are both hyperbolic-type aspherical surfaces capable of well improving the field curvature aberration.

Description

【Technical Field】 [0001] The invention relates to an optical lens, in particular to a wide-angle optical lens applied to high-pixel mobile phones and ultra-thin high-quality cameras. 【Background technique】 [0002] The current mobile phone digital lenses generally have such shortcomings: all-plastic lens structure, difficult to improve pixels, and low tax and profit for imaging images. The mainstream camera phones on the market are mainly all-plastic lens with less than 13 million pixels. The image quality of the captured images is not ideal in terms of overall clarity or uniformity of illumination. They can only be used as standby images or general Appreciation, which is far from enough to print exquisite photos. Compared with SLR cameras, the image quality is significantly different after zooming in. [0003] In order to overcome the above shortcomings, the present invention has made a lot of improvements. [Content of the invention] [0004] The present invention overcomes the s...

The current mainstream camera phones in the market are mainly all-plastic lenses with less than 13 million pixels. The image quality of the captured images is not ideal in terms of overall clarity or uniformity of illumination. They can only be used as standby screens or general Appreciation, but far from enough to print exquisite photos, compared with SLR cameras, the image quality difference is obvious after zooming in
