Document Type and Number:
WIPO Patent Application WO/2021/097925
Kind Code:
A1
Abstract:
A camera optical 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, a third lens (L3) having a negative refractive power, a fourth lens (L4) having a positive refractive power, and a fifth lens (L5) having a negative refractive power, and the following relationships are satisfied: -0.45 ≤ f1 / f2 ≤ -0.28; -2.80 ≤ f2 / f ≤ -1.80; -1.70 ≤ (R1 + R2) / (R1 − R2) ≤ -1.35; 1.24 ≤ (R3 + R4) / (R3 − R4) ≤ 1.65; 1.10 ≤ (R7 + R8) / (R7 − R8) ≤ 1.40; 0.88 ≤ d8 / d9 ≤ 1.40. The camera optical lens (10) has good optical performance, and meets wide angle and ultra-thinness design requirements.
