Title:
PHOTOGRAPHING OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2022/052269
Kind Code:
A1
Abstract:
A photographing optical lens (10). The photographing optical lens (10) comprises six lenses, the six lenses successively comprising, from an object side to an image side: a first lens (L1) having positive refractive power, a second lens (L2) having negative refractive power, a third lens (L3) having negative refractive power, a fourth lens (L4) having positive refractive power, a fifth lens (L5) having negative refractive power, and a sixth lens (L6). The Abbe number of the first lens (L1) is v1, the on-axis distance between the image side surface of the fourth lens (L4) and the object side surface of the fifth lens (L5) is d8, and the on-axis thickness of the fifth lens (L5) is d9; moreover, the following relational expressions are satisfied: 65.00≤v1≤90.00; and 2.00≤d8/d9≤8.00. The photographing optical lens (10) has good optical properties, and satisfies the design requirements of large aperture, long focal length, and ultra-thinness.
