Title:
OPTICAL CAMERA LENS
Document Type and Number:
WIPO Patent Application WO/2022/047991
Kind Code:
A1
Abstract:
An optical camera lens (10) sequentially comprises, 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, and a third lens (L3) having a positive refractive power. The camera optical lens (10) has an overall focal length f, the first lens (L1) has a focal length f1, the third lens (L3) has a focal length f3, an object side face of the first lens (L1) has a radius of curvature R1, an image side face of the first lens (L1) has a radius of curvature R2, an object side face of the second lens (L2) has a radius of curvature R3, an image side face of the second lens (L2) has a radius of curvature R4, an object side face of the third lens (L3) has a radius of curvature R5, an image side face of the third lens (L3) has a radius of curvature R6, the on-axis distance from the image side face of the second lens (L2) to the object side face of the third lens (L3) is d4, the third lens (L3) has an on-axis thickness d5, and the following relational expressions are met: 0.75 ≤ f1/f ≤ 0.95, 1.20 ≤ f3/f ≤ 2.00, 0 ≤ (R1+R2)/(R1-R2) ≤ 0.80, -3.50 ≤ (R3+R4)/(R3-R4) ≤ -1.50, -8.00 ≤ (R5+R6)/(R5-R6) ≤ -2.50, and 1.50 ≤ d5/d4 ≤ 4.00. The optical camera lens (10) has good optical properties, such as a large aperture, a wide angle, and an ultra-thin thickness.
