Document Type and Number:
WIPO Patent Application WO/2022/047982
Kind Code:
A1
Abstract:
A photographing optical lens (10), sequentially comprising nine lenses in total, from an object side to an image side: a first lens (L1) having positive refractive power, a second lens (L2) having negative refractive power, a third lens (L3) having positive refractive power, a fourth lens (L4) having positive refractive power, a fifth lens (L5) having positive refractive power, a sixth lens (L6) having negative refractive power, a seventh lens (L7), 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) is f; the focal length of the first lens (L1) is f1; the on-axis thickness of the fifth lens (L5) is d9; the on-axis 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: 2.00≤f1/f≤4.50; and 3.00≤d9/d10≤12.00. The photographing optical lens (10) has good optical properties, and satisfies the design requirements of large aperture, wide angle, and ultra-thinness.
