Document Type and Number:
WIPO Patent Application WO/2022/047999
Kind Code:
A1
Abstract:
The present invention relates to the field of optical lenses. Disclosed is a photographing optical lens. The photographing optical lens comprises a total of nine lens members; the nine lens members in sequence from an object side to an image side are: a first lens member, a second lens member, a third lens member, a fourth lens member, a fifth lens member, a sixth lens member, a seventh lens member, an eighth lens member, and a ninth lens member; the second lens member has a negative refractive power. A focal length of the photographing optical lens is f, a focal length of the first lens member is f1, an on-axis thickness of the fourth lens member is d7, an on-axis distance from an image-side surface of the fourth lens member to an object-side surface of the fifth lens member is d8, and the following relation expressions are satisfied: 2.00≤f1/f≤5.50, and 2.00≤d7/d8≤10.00. The photographing optical lens provided in the present invention satisfies the design requirements of a large aperture, a wide angle, and ultra thinness while having a good optical performance.
