Document Type and Number:
WIPO Patent Application WO/2022/047981
Kind Code:
A1
Abstract:
An optical camera lens (10) comprises nine lenses in total, namely, 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 positive refractive power, a fourth lens (L4) having a negative refractive power, a fifth lens (L5) having a positive refractive power, a sixth lens (L6) having a negative refractive power, a seventh lens (L7) having a positive refractive power, an eighth lens (L8) having a positive refractive power and a ninth lens (L9) having a negative refractive power in sequence, wherein the optical camera lens (10) has a focal length f, the first lens (L1) has a focal length f1, the seventh lens (L7) has an on-axis thickness d13, the on-axis distance from an image side face of the seventh lens (L7) to an object side face of the eighth lens (L8) is d14, and the following relational expressions are met: 2.20 ≤ f1/f ≤ 5.00 and 3.00 ≤ d13/d14 ≤ 15.00. The optical camera lens (10) meets the design requirements of a large aperture, a wide angle, and an ultra-thin thickness, while also having a good optical performance.
