Title:
PHOTOGRAPHING OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2022/088350
Kind Code:
A1
Abstract:
Disclosed is a photographing optical lens (10), sequentially comprising from the object side to the image side: a first lens (L1), a second lens (L2), a third lens (L3), a fourth lens (L4), a fifth lens (L5), and a sixth lens (L6). The focal length of the photographing optical lens (10) is f, the focal length of the first lens (L1) is f1, the focal length of the second lens (L2) is f2. The central radius of curvature of the object side surface of the fourth lens (L4) is R7, the central radius of curvature of the image side surface of the fourth lens (L4) is R8, the central radius of curvature of the object side surface of the fifth lens (L5) is R9, and the central radius of curvature of the image side surface of the fifth lens (L5) is R10. The on-axis distance from the image side surface of the fourth lens (L4) to the object side surface of the fifth lens (L5) is d8, the on-axis thickness from the image side of the fifth lens (L5) to the object side surface of the sixth lens (L60 is d10, and the following relational expressions are satisfied: -4.00 ≤ f1/f ≤ -2.20; 1.50 ≤ f2/f ≤ 3.50; 3.00 ≤ R7/R8 ≤ 8.00; 1.50 ≤ (R9+R10)/(R9-R10) ≤ 8.00; and 1.50 ≤ d8/d10 ≤ 5.00. The photographing optical lens (10) meets wide angle and ultra thin design requirements while also having good optical performance.
