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 , although the common five-element lens can correct most of the optical aberrations of the optical system, it is not easy to meet the design requirements of low total track length (TTL)

Abstract

The invention relates to the field of optical lenses, and discloses a camera optical lens. The camera optical lens sequentially comprises an aperture, a first lens, a second lens, a third lens, a fourth lens and a fifth lens from an object side to an image side. The camera optical lens meets the following relational expression: 3<f / r1-f / r2+f*D1 / (r1*r2)<4.5, -1.2<f1 / f4<-0.2, f / r1<3.399. Therefore, the design requirements of low TTL can be met by the camera optical lens provided by the invention.

Description

technical field [0001] The invention relates to the field of optical lenses, in particular to a camera optical lens. 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 the market. [0003] In order to obtain better imaging quality, traditional lenses mounted on mobile phone cameras mostly adopt a three...
