Title:
CAMERA OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2021/168910
Kind Code:
A1
Abstract:
A camera optical lens (10, 20, 30, 40). The camera optical lens (10, 20, 30, 40) 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 positive refractive power, a fourth lens (L4), a fifth lens (L5) having a positive refractive power, a sixth lens (L6) having a positive refractive power, and a seventh lens (L7) having a negative refractive power; and the following relational expressions are satisfied: 1.70 ≤ f6/f ≤ 5.00; -4.00 ≤ R14/R13 ≤ -1.00; -5.00 ≤ f2/f ≤ -2.00; and 1.00 ≤ d8/d9 ≤ 2.00. The camera optical lens (10, 20, 30, 40) has optical performance, such as large aperture, wide angle, and ultra thinness.
