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 take into account the low total optical length (TTL, Total Track Length) and large image height while having excellent optical characteristics, and it cannot be very good Suitable for high-resolution portable imaging devices

Abstract

The invention relates to the field of optical lenses and discloses an imaging optical lens successively comprising, from an object side to an image side, an aperture, a first lens, a second lens, a third lens, a fourth lens, and a fifth lens. The imaging optical lens satisfies the following relation: 0.75<f1 / f<0.80, 2.0<f2 / f< 1.9, 7<f3 / f< 6, 0.5<f4 / f<0.6, and 0.5<f5 / f< 0.4. The imaging opticallens achieves low TTL and a high image height while achieving a large aperture, and can be well suitable for high-pixel portable imaging elements.

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...
