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 cannot meet the requirements of large aperture and have the advantages of good imaging performance

Abstract

The invention relates to a field of optical lens and discloses a camera optical lens. The camera optical lens includes a diaphragm, a first lens, a second lens, a third lens, a fourth lens and a fifth lens arranged successively from an object side to an image side. The following relational expression is met. 0.75<f1 / f<0.80, 2.0<f2 / f< 1.85, 7<f3 / f< 6,0.53<f4 / f<0.55, 0.48<f5 / f< 0.45; 11<v2 / n2<14,1.15<n2 / n5<1.25,0.03<d3 / TTL<0.035,0.15<d3 / d7<0.17; 2.3<(r3 r6) / (r3+r6)< 3.3. The camera optical lens has a large diaphragm and also has an advantage of good imaging quality.

Description

Technical field [0001] The present invention relates to the field of optical lenses, in particular to an imaging optical lens suitable for portable terminal equipment such as smart phones and digital cameras, as well as 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 increased. The photosensitive devices of general photographic lenses are nothing more than charge coupled devices (CCD) or complementary metal oxide semiconductor devices (Complementary Metal -OxideSemicondctor Sensor, CMOS Sensor), and due to the advancement of semiconductor manufacturing technology, the pixel size of photosensitive devices has been reduced, coupled with the development trend of current electronic products with good functions, thin and short appearance, so they have good The miniaturized camera lens with image quality has become the mainstream in the current market.
