Camera shooting optical lens

Abstract

The present invention relates to the optical lens field, and discloses a camera shooting optical lens. The lens comprises from an object side to an image side in order: an aperture, a first lens with positive refraction power, a second lens with negative refraction power, a third lens with negative refraction power, a fourth lens with positive refraction power and a fifth lens with negative refraction power. The camera shooting optical lens satisfies the relation as follows: 0.70<f1 / f<0.80, 2.0<f2 / f< 1.7, 14<f3 / f< 10, 0.59<f4 / f<0.62, 0.52<f5 / f< 0.48, 1.09<(f3 f4) / (f3+f4)<1.12 and other relations. The camera shooting optical lens can satisfy the low TTL and the large aperture design requirement and has good sensitivity appearance.

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 -OxideSemiconductor 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 good Miniaturized camera lenses with image quality have become the mainstream in th...

Problems solved by technology

However, with the development of technology and the increase of diversified needs of users, as the pixel area of ​​the photosensitive device continues to shrink, and the system’s requirements for imaging quality continue to increase, the five-element lens structure gradually appears in the lens design, but , the common five-element lens cannot meet the design requirements of low TTL (Total Track Length, optical full length) and large aperture
