Camera shooting optical lens

Abstract

The invention relates to the field of optical lenses, and discloses a camera shooting optical lens. The camera shooting optical lens sequentially comprises the following components from an object sideto an image side: a first lens having positive refractive power, a second lens having negative refractive power, a third lens having negative refractive power, a fourth lens having positive refractive power, and a fifth lens having negative refractive power; the focal length of the camera shooting optical lens is f, the focal length of the first lens is f1, the on-axis thickness of the third lens is d5, the on-axis distance from an image side face of the third lens to an object side face of the fourth lens is d6, the radius of curvature of the object side face of the fourth lens is R7, the radius of curvature of the image side face of the fourth lens is R8, and the following relational expressions are satisfied: f1 / f is greater than or equal to 0.40 and is less than or equal to 0.60; d6 / d5 is greater than or equal to 7.00 and is less than or equal to 15.00; and (R7 + R8) / (R7-R8) is greater than or equal to 6.00 and is less than or equal to 30.00. The camera shooting optical lens provided by the invention has good optical performance and meets the design requirements of long focal length and ultra-thin.

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...

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. Common Although the five-element 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 cannot meet the requirements of long focal length, Ultra-thin design requirements
