Document Type and Number:
WIPO Patent Application WO/2020/140502
Kind Code:
A1
Abstract:
Disclosed is an optical camera lens (10), sequentially comprising from an object side to an image side: an aperture (S1), a first lens (L1) with a positive refractive power, a second lens (L2) with a positive refractive power, a third lens (L3) with a negative refractive power, a fourth lens (L4) with a negative refractive power, a fifth lens (L5) with a positive refractive power, and a sixth lens (L6) with a negative refractive power, wherein the on-axis thickness of the first lens (L1) is d1, the on-axis distance from an image side face of the first lens (L1) to an object side face of the second lens (L2) is d2, the Abbe number of the first lens (L1) is v1, and the Abbe number of the third lens (L3) is v3. The following relationships are satisfied: 8.00 ≤ d1/d2 ≤ 12.00, and 2.80 ≤ v1/v3 ≤4.00. The optical camera lens (10) has a good optical performance and also satisfies a design requirement for ultra-thinness.
