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 six-element lens structure gradually appears in the lens design. Common Although the six-element lens already has good optical performance, its focal power, lens spacing and lens shape settings are still unreasonable, resulting in a lens structure that cannot meet the requirements of long focal length, Ultra-thin design requirements

Description

[0001] 【Technical field】 [0002] 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. [0003] 【Background technique】 [0004] 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, they have good Miniaturized camera lenses with image quality have becom...
