Abstract
The invention provides a camera shooting optical lens. The camera shooting optical lens comprises five lenses including a first lens with positive refractive power, a second lens with negative refractive power, a third lens with negative refractive power, a fourth lens with positive refractive power and a fifth lens with negative refractive power in sequence from an object side to an image side; the focal length of the whole camera shooting optical lens is f; the focal length of the first lens is f1; the focal length of the third lens is f3; the curvature radius of the object side surface of the second lens is R3; the curvature radius of the image side surface of the second lens is R4; the curvature radius of the object side surface of the third lens is R5, the curvature radius of the image side surface of the third lens is R6, the on-axis thickness of the fourth lens is d7, the on-axis distance from the image side surface of the fourth lens to the object side surface of the fifth lensis d8, and the following relational expressions are satisfied: 0.70 < = f1 / f < =0.90; -35.00 < = f3 / f < = -10.00; 4.00 < = R3 / R4 < = 12.00; 3.00 < = (R5 + R6) / (R5-R6) < = 20.00; 2.00 < = d7 / d8 < = 4.50. The camera shooting optical lens has good optical performance, and meets the design requirements of 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] 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...
