Camera Optical Lens

Abstract

The present invention relates to the field of optical lenses, and discloses a photographic optical lens, which comprises in sequence from the object side to the image side: a first lens with negative refractive power, a second lens with positive refractive power, and a second lens with positive refractive power. A third lens with a refractive power, a fourth lens with a negative refractive power, a fifth lens with a positive refractive power, and a sixth lens with a negative refractive power; wherein, the Abbe number of the third lens is v3, and the The focal length of the fourth lens is f4, the focal length of the fifth lens is f5, the central radius of curvature of the object side of the first lens is R1, the central radius of curvature of the image side of the first lens is R2, and satisfy The following relationships: 65.00≤v3≤95.00; R2 / R1≤‑2.00; ‑10.00≤f4 / f5≤‑2.00. The imaging optical lens provided by the invention not only has good optical performance, but also satisfies the design requirements of wide-angle and ultra-thin.

Description

technical field [0001] The invention relates to the field of optical lenses, in particular to an imaging optical lens suitable for portable terminal devices such as smart phones and digital cameras, and imaging devices such as monitors and PC lenses. Background technique [0002] In recent years, with the rise of smart phones, the demand for miniaturized photographic lenses has been increasing, and the photosensitive devices of general photographic lenses are nothing more than photocoupled devices (Charge Coupled Device, CCD) or complementary metal oxide semiconductor devices (Complementary Metal -Oxide Semiconductor Sensor, CMOS Sensor), and due to the improvement of semiconductor manufacturing process technology, the pixel size of photosensitive devices has been reduced, and today's electronic products are developing with good functions and thin, light and small appearance. Therefore, it has Miniaturized camera lenses with good imaging quality have become the mainstream in...

Problems solved by technology

However, with the development of technology and the increase of diversified needs of users, the pixel area of ​​the photosensitive device is continuously reduced, and the requirements of the system for imaging quality are continuously improved. Although the common six-piece lens already has better optical performance, but its focal power, lens spacing and lens shape settings are still unreasonable to a certain extent, resulting in a lens structure that cannot meet the wide-angle and ultra-thin design requirements while having good optical performance
