Document Type and Number:
WIPO Patent Application WO/2022/011741
Kind Code:
A1
Abstract:
A camera optical lens (10), comprising seven lenses in total. The seven lenses are sequentially, from an object side to an image side: a first lens (L1) having positive refractive power, a second lens (L2) and a third lens (L3) having negative 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, and a seventh lens (L7) having negative refractive power; the focal length of the first lens (L1) is f1, the focal length of the sixth lens (L6) is f6, the focal length of the seventh lens (L7) is f7, and the overall focal length of the camera optical lens (10) is f; an on-axis distance from an image side surface of the second lens (L2) to an object side surface of the third lens (L3) is d4, and an on-axis thickness of the third lens (L3) is d5; moreover, the following relational expressions are satisfied: 0.50≤f1/f≤0.80; 1.50≤f6/f7≤5.00; and 1.20≤d4/d5≤2.00. The camera optical lens (10) has optical properties of a large aperture, a long focal length, and ultra-thinness.
