Document Type and Number:
WIPO Patent Application WO/2021/128380
Kind Code:
A1
Abstract:
Disclosed is an optical camera lens (10, 20, 30), which relates to the field of optical lenses. The optical camera lens (10, 20, 30) sequentially comprises, 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 optical camera lens (10, 20, 30) 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 an object-side surface of the first lens (L1) is R1, the radius of curvature of an image-side surface of the first lens (L1) is R2, the axial thickness of the first lens (L1) is d1, the axial distance from the image-side surface of the first lens (L1) to an object-side surface of the second lens (L2) is d2, and the following relational expressions are satisfied: f1 ≥ 0.00 mm; 1.60 ≤ f2/f ≤ 3.50; 3.00 ≤ d1/d2 ≤ 30.00; and -0.90 ≤ (R1+R2)/(R1-R2) ≤-0.20. The optical camera lens (10, 20, 30) has a good optical performance and meets the design requirements of a large aperture, a wide angle, and ultra thinness.
