Title:
OPTICAL CAMERA LENS
Document Type and Number:
WIPO Patent Application WO/2022/088351
Kind Code:
A1
Abstract:
An optical camera lens (10), sequentially comprising, from an object side to an image side: a first lens (L1) having a positive refractive power, a second lens (L2) having a negative refractive power, a third lens (L3) having a negative refractive power, a fourth lens (L4), and a fifth lens (L5) having a negative refractive power, wherein the optical camera lens (10) has a focal length f; the first lens (L1) has a focal length f1; the third lens (L3) has a focal length f3; the on-axis distance from an image-side face of the third lens (L3) to an object-side face of the fourth lens (L4) is d6; the fourth lens (L4) has an on-axis thickness d7; an object-side face of the fifth lens (L5) has a center curvature radius R9; an image-side face of the fifth lens (L5) has a center curvature radius R10; and the following relational expressions are satisfied: 0.30 ≤ f1/f ≤ 0.50; -4.00 ≤ f3/f ≤ -1.20; 2.00 ≤ d6/d7 ≤ 8.00; and 3.00 ≤ R9/R10 ≤ 10.00. The optical camera lens (10) has good optical properties and also meets the design requirements of having a long focal length and being ultra-thin.
