Title:
PHOTOGRAPHING OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2022/088364
Kind Code:
A1
Abstract:
A photographing optical lens (10). The photographing optical lens (10) sequentially comprises from the object side to the image side: a first lens (L1) having a positive refractive power, a second lens (L2), a third lens (L3), a fourth lens (L4), a fifth lens (L5), a sixth lens (L6), a seventh lens (L7), and an eighth lens (L8), the first lens (L1) having a positive refractive power, wherein the optical total length of the photographing optical lens (10) is TTL, the focal length of the photographing optical lens (10) is f, the focal length of the second lens (L2) is f2, the radius of the center curvature of the object-side surface of the sixth lens (L6) is R11, the radius of the center curvature of the image-side surface of the sixth lens (L6) is R12, and the following relationships are satisfied: 0.95≤f/TTL, 3.20≤f2/f≤5.00, and 0.20≤(R11+R12)/(R11-R12)≤0.90. The photographing optical lens (10) has a good optical performance, and also meets design requirements for long focal length and ultra-thinness.
