Abstract

The present invention provides a kind of photographing optical lens, comprises in sequence from object side to image side: first lens, second lens, third lens, fourth lens and fifth lens; Wherein, the curvature radius of the object side surface of second lens is R3, the radius of curvature of the image side of the second lens is R4, the radius of curvature of the object side of the third lens is R5, the radius of curvature of the image side of the third lens is R6, the image side of the second lens reaches the third lens The on-axis distance of the object side is d4, the on-axis distance from the image side of the third lens to the object side of the fourth lens is d6, the image height of the imaging optical lens is IH, the total optical length of the imaging optical lens is TTL, and satisfies the following Relational formula: 1.50≤(R5+R6) / (R5-R6); 0.40≤d4 / d6≤1.25; 1.00≤TTL / IH≤1.30; 1.00≤(R3+R4) / (R3-R4)≤2.40. The camera optical lens not only has good optical performance, but also meets the design requirements of large aperture, 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] In order to obtain better imaging quality, traditional lenses mounted on mobile phone cameras mostly adopt a three-element or four-element lens structure. However, with the development of technology and the increase of diversified needs of users, as the pixel area of ​​the photosensitive device continue...
