Document Type and Number:
WIPO Patent Application WO/2022/052266
Kind Code:
A1
Abstract:
A photographing optical lens (10, 20, 30), relating to the field of optical lenses. The photographing optical lens (10, 20, 30) comprises nine lenses in total, and the nine lenses are sequentially, from an object side to an image side: a first lens (L1) having positive refractive power, a second lens (L2) having positive refractive power, a third lens (L3) having negative refractive power, a fourth lens (L4) having positive refractive power, a fifth lens (L5) having negative refractive power, a sixth lens (L6) having negative refractive power, a seventh lens (L7) having positive refractive power, an eighth lens (L8) having positive refractive power, and a ninth lens (L9) having negative refractive power. The focal length of the photographing optical lens (10, 20, 30) is f, the focal length of the first lens (L1) is f1, the on-axis thickness of the fourth lens (L4) is d7, the on-axis distance from the image side surface of the fourth lens (L4) to the object side surface of the fifth lens (L5) is d8, and the following relational expressions are satisfied: 3.50≤f1/f≤6.50, and 2.00≤d7/d8≤10.00. The photographing optical lens (10, 20, 30) has good optical properties, and satisfies the design requirements of large aperture, wide angle, and ultra-thinness.
