Document Type and Number:
WIPO Patent Application WO/2021/127892
Kind Code:
A1
Abstract:
An optical image capture lens (10), the optical image capture lens (10) sequentially comprising from the object side to the 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 negative refractive power, and a sixth lens (L6) having positive refractive power; the focal length of the first lens (L1) is f1, the focal length of the second lens (L2) is f2, the focal length of the fourth lens (L4) is f4, and the focal length of the fifth lens (L5) is f5; and the on-axis distance from the image side surface of the first lens (L1) to the object side surface of the second lens (L2) is d2, and the on-axis thickness of the third lens (L3) is d3, and the following relationships are satisfied: -4.00≤f1/f2≤-1.50; 3.00≤d2/d3≤10.00; and -5.00≤f4/f5≤-2.00. The optical image capture lens (10) has a good optical performance while simultaneously satisfying requirements for ultra-thinness and a long focal length.
