Title:
PHOTOGRAPHING OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2021/031284
Kind Code:
A1
Abstract:
Disclosed is a photographing optical lens (10), sequentially comprising, from an object side to an image side, a first glass plate (G1), a first lens (L1) having a negative refractive power, a second lens (L2) having a positive refractive power, and a third lens (L3) having a positive refractive power, wherein the third lens (L3) has a focal length of f4, the photographing optical lens (10) has a total system focal length of f, the first lens (L1) has an Abbe number of v2, the second lens (L2) has an Abbe number of v3, the third lens (L3) has a refractive index of n4, the second lens (L2) has an on-axis thickness of d5, and the on-axis distance from an image-side face of the second lens (L2) to an object-side face of the third lens (L3) is d6, satisfying the following relationships: 10.00 ＜ f4/f ＜ 31.00; 2.80 ＜ v3/v2 ＜ 4.00; 1.60 ＜ n4 ＜ 2.10; and 5.00 ＜ d5/d6 ＜ 21.00. The photographing optical lens has a good optical performance, and simultaneously meets the wide-angle, large-aperture and fingerprint identification design requirements.
