Abstract
The invention discloses an optical lens component, comprising a diaphragm and a lens group which comprises a first lens, a second lens and a third lens which are coaxial and serially arranged from the object side to the image side, the first lens comprises a first surface which is close to the object side and a second surface which is close to the image side, the second lens comprises a third surface which is close to the object side and a fourth surface which is close to the image side, the third lens comprises a fifth surface which is close to the object side and a sixth surface which is close to the image side, the first, the second, the third, the fourth, the fifth and the sixth surfaces are aspheric surfaces, and coordinates of all the points on the aspheric surfaces can meet an aspheric formula. The optical lens component allows the overall optical length of the optical lens component of the invention to be relatively shorter through adopting the aspheric lens with the specific parameters. The optical lens component of the invention can allow the image height to be more than 4.70mm, thereby being fit an imaging chip with 2 million pixels and other high pixels.
Description
technical field [0001] The invention relates to an optical device, in particular to an optical lens assembly. Background technique [0002] With the advancement of technology, the camera function of mobile phones is becoming more and more powerful, the image data processing speed of mobile phones is constantly accelerating, the picture editing functions are constantly enriched, and the imaging quality of mobile phone cameras is also steadily improving. The pixels of mobile phone cameras have gradually transitioned from the initial 300,000 to the current 1.3 million. At present, mobile phone manufacturers have configured mobile cameras with 2 million pixels, 3.2 million pixels, or even higher pixels on their high-end mobile phones. However, keeping the mobile phone thin, light and small while achieving high pixels has brought great challenges to the design of optical lens components. Contents of the invention [0003] In order to overcome the above disadvantages, the pres...
