Document Type and Number:
WIPO Patent Application WO/2021/119892
Kind Code:
A1
Abstract:
The present invention provides a camera optical lens, sequentially comprising, from an object side to an image side, a first lens having positive refractive power, a second lens having negative refractive power, a third lens having positive refractive power, a fourth lens having positive refractive power, and a fifth lens having negative refractive power, where the following relationships are satisfied: -2.10 ≤ f2 / f ≤ -1.50; 0.85 ≤ f4 / f ≤ 1.20; -2.50 ≤ (R1 + R2) / (R1 - R2) ≤ -1.10; 0.40 ≤ (R9 + R10) / (R9 - R10) ≤ 1.00; 1.00 ≤ d4 / d5 ≤ 1.50; 1.00 ≤ (R3 + R4) / (R3 - R4) ≤ 1.50. The camera optical lens has good optical performance, and meets large-aperture, wide-angle, and ultra-thinness design requirements.
