Document Type and Number:
WIPO Patent Application WO/2022/052265
Kind Code:
A1
Abstract:
An optical camera lens (10, 20, 30), relating to the field of optical lenses. The optical camera lens (10, 20, 30) comprises nine lenses in total. From the object side to the image side, the nine lenses are sequentially: a first lens (L1) having positive refractive power, a second lens (L2) having positive refractive power, a third lens (L3), a fourth lens (L4), a fifth lens (L5), a sixth lens (L6) having positive refractive power, a seventh lens (L7) having negative refractive power, an eighth lens (L8) having positive refractive power, and a ninth lens (L9) having negative refractive power, 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 axial thickness of the fifth lens (L5) is d9, and the axial distance from the image side surface of the fifth lens (L5) to the object side surface of the sixth lens (L6) is d10, and the following relational expressions are satisfied: 3.80≤f1/f≤7.50, and 3.00≤d9/d10≤12.00. The optical camera lens (10, 20, 30) satisfies large-aperture, wide-angle, and ultra-thin design requirements while having good optical properties.
