Problems solved by technology

Moreover, 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, five-element and six-element lens structures gradually appear in the lens In the design, although the common six-piece lens already has good optical performance, its focal power, lens spacing and lens shape settings still have certain irrationality, resulting in a lens structure that has good optical performance and cannot Meet the design requirements of large aperture, ultra-thin, wide-angle

Abstract

The invention relates to the field of optical lenses, and discloses a camera shooting optical lens. The camera shooting optical lens sequentially comprises a first lens, a second lens, a third lens, afourth lens, a fifth lens and a sixth lens from an object side to an image side. A focal length of the camera shooting optical lens is f; the focal length of the fourth lens is f4; and an on-axis distance from an image side surface of the first lens to an object side surface of the second lens is d2, an on-axis thickness of the second lens is d3, a curvature radius of the object side surface of the fifth lens is R9, the curvature radius of the image side surface of the fifth lens is R10, and the following relational expressions are satisfied:-5.00< / =f4 / f< / =-2.00; 1.20< / =d2 / d3< / =2.00; and 1.40< / =(R9+R10) / (R9-R10)< / = 4.00. The camera shooting optical lens provided by the invention has good optical performance and meets design requirements of a large aperture, a wide angle and ultra thinness.

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...
