Abstract
The invention discloses an optical lens component, comprising a diaphragm and a lens group; wherein, the lens group comprises a first lens, a second lens and a third lens which have the same axis and are sequentially arranged from the object to the image; the diaphragm is arranged in front of the first lens and close to the object; the first lens comprises a first surface close to the object and a second surface close to the image; the second lens comprises a third surface close to the object and a fourth surface close to the image; the third lens comprises a fifth surface close to the object and a sixth surface close to the image; the first surface, the second surface, the third surface, the fourth surface, the fifth surface and the sixth surface are non-spherical surfaces; the coordinate values of all points on the non-spherical surfaces meet the non-spherical formula. By adopting the non-spherical lens with specific parameters, the optical lens component has relatively short optical total length. The optical lens component leads the image to achieve more than 4.70mm and can be matched with imaging chips with high pixel such as 2 million pixels.
Description
technical field [0001] The invention relates to an optical device, in particular to an optical lens assembly. Background technique [0002] With the continuous advancement of science and technology and the continuous advancement of fashion trends, the camera function of small mobile phones is becoming more and more powerful, the image data processing speed is continuously accelerated, the image editing functions are continuously enriched, and the image quality of mobile phone cameras is also steadily improving. From the initial 300,000 pixels, to the current 1.3 million pixels. Nowadays, major mobile phone manufacturers have equipped their high-end mobile phones with 2-megapixel, 3.2-megapixel or even higher-pixel mobile phone cameras. The design of chip technology and optical lens is a big challenge. Contents of the invention [0003] In order to overcome the above disadvantages, the present invention proposes an optical lens assembly with relatively short total optical...
