Document Type and Number:
WIPO Patent Application WO/2022/041382
Kind Code:
A1
Abstract:
An optical camera lens (10), comprising five lenses in total. The five lenses from an object side to an image side are: 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, and a fifth lens (L5) having negative refractive power. The overall focal length of the optical camera lens (10) is f, the focal length of the first lens (L1) is f1, the central curvature radius of the object side of the second lens (L2) is R3, the central curvature radius of the image side of the second lens (L2) is R4, the on-axis thickness of the third lens (L3) is d5, the on-axis distance from the image side of the third lens (L3) to the object side of the fourth lens (L4) is d6, and the following relationships are satisfied: 1.10≤f1/f≤1.50, 0.40≤R3/R4≤1.00 and 1.00≤d5/d6≤2.00. The optical camera lens (10) not only has good optical performance, but also meets the design requirements for large aperture, wide angle and ultra-thinness.
