Document Type and Number:
WIPO Patent Application WO/2022/057042
Kind Code:
A1
Abstract:
An optical camera lens (10). The optical camera lens (10) comprises nine lenses. From an object side to an image side, the nine lenses sequentially are 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), an eighth lens (L8), and a ninth lens (L9); the second lens (L2) has positive refractive power; and the focal length of the optical camera lens (10) is f, the focal length of the first lens (L1) is f1, the axial thickness of the second lens (L2) is d3, an axial distance between the image side surface of the second lens (L2) and the object side surface of the third lens (L3) is d4, and the following relation expressions are satisfied: 1.80≤f1/f≤3.20, and 2.00≤d3/d4≤8.00. The optical camera lens (10) has good optical properties, and satisfies the design requirements of large aperture, wide angle, and ultra-thinness.
