Document Type and Number:
WIPO Patent Application WO/2022/047996
Kind Code:
A1
Abstract:
Provided is a camera optical lens (30,40). The camera optical lens (10,20) sequentially contains, from an object side to an image side: a first lens (L1), a second lens (L2), a third lens (L3), a fourth lens (L4), a fifth lens (L5), a sixth lens (L6), a seventh lens (L7) and an eighth lens (L8), wherein the focal length of the camera optical lens (30,40) is f, the focal length of the first lens (L1) is f1, the focal length of the second lens (L2) is f2, the radius of curvature of the object side face of the sixth lens (L6) is R11, the radius of curvature of the image side face of the sixth lens (L6) is R12, the on-axis thickness of the fifth lens (L5) is d9, and the on-axis distance between the image side face of the fifth lens (L5) and the object side face of the sixth lens (L6) is d10, which satisfy the following relational expressions: -2.80 ≤ f1/f ≤ -1.20; f2 ≤ 1.90; 1.20 ≤ (R11 + R12)/(R11 - R12) ≤ 5.00; and 0.70 ≤ d9/d10 ≤ 1.00. The camera optical lens (10, 20, 30, 40) meets the design requirements of a large aperture, a wide angle and ultra-thinness while having a good optical performance.
