Title:
OPTICAL CAMERA LENS
Document Type and Number:
WIPO Patent Application WO/2022/052264
Kind Code:
A1
Abstract:
An optical camera lens (10) comprise nine lenses in total, namely, a first lens (L1) having a positive refractive power, a second lens (L2) having a positive refractive power, a third lens (L3) having a negative refractive power, a fourth lens (L4) having a positive refractive power, a fifth lens (L5) having a negative refractive power, a sixth lens (L6) having a positive refractive power, a seventh lens (L7) having a positive refractive power, an eighth lens (L8) having a positive refractive power, and a ninth lens (L9) having a negative refractive power in sequence from an object side to an image side. The optical camera lens (10) has a focal length f, the first lens (L1) has a focal length f1, the sixth lens (L6) has an on-axis thickness d11, the on-axis distance from an image side face of the sixth lens (L6) to an object side face of the seventh lens (L7) is d12, and the following relational expressions are met: 3.50 ≤ f1/f ≤ 7.00 and 2.00 ≤ d11/d12 ≤ 9.00. The optical camera lens (10) meets the design requirements of a large-aperture, a wide angle, and an ultra-thin thickness while also having good optical properties.
