Abstract

The invention provides a photographing optical lens. In the direction from the object side to the image side, the photographing optical lens successively includes an aperture, a first lens with positive refractive power, a second lens with negative refractive power, and a second lens with negative refractive power. A third lens with positive refractive power, a fourth lens with positive refractive power and a fifth lens with negative refractive power, wherein the focal length of the imaging optical lens is f, the focal length of the first lens is f1, and the focal length of the third lens is The focal length is f3, the radius of curvature of the image side of the second lens is R2, the radius of curvature of the object side of the fifth lens is R9, and the radius of curvature of the image side of the fifth lens is R10, the above parameters satisfy the following relationship: 5.1≤R2 / f≤5.2; 3.4≤R9 / R10≤3.5; 8.3≤(f1+f3) / f≤8.5; this camera optical lens not only has good optical performance, but also meets the design requirements of wide-angle and ultra-thin.

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] With the development of camera technology, camera optical lenses are widely used in various electronic products, such as smart phones, digital cameras and so on. For the convenience of portability, people are increasingly pursuing thinner and lighter electronic products. Therefore, miniaturized camera optical lenses with good imaging quality have become the mainstream of the current market. [0003] The camera optical lenses on traditional electronic products mostly adopt four-piece, five-piece, six-piece or even seven-piece lens structures. The shape setting is insufficient, resulting in insufficient wide-angle and ultra-thin imaging optical lenses. [0004] Therefore, it is necessary to prov...
