Title:
OPTICAL CAMERA LENS
Document Type and Number:
WIPO Patent Application WO/2022/057049
Kind Code:
A1
Abstract:
An optical camera lens (10), comprising five lenses in total, which sequentially comprise, from an object side to an image side, a first lens (L1) having a positive refractive power, a second lens (L2) having a positive refractive power, a third lens (L3) having a positive refractive power, a fourth lens (L4) having a negative refractive power and a fifth lens (L5) having a negative refractive power. The optical camera lens (10) has a focal length f, the first lens (L1) has a focal length f1, the second lens (L2) has an on-axis thickness d3, the third lens (L3) has an on-axis thickness d5, an object side face of the fourth lens (L4) has a central radius of curvature R7, an image side face of the fourth lens (L4) has a central radius of curvature R8, and the following relational expressions are met: 1.20 ≤ f1/f ≤ 4.00, 1.80 ≤ d5/d3 ≤ 3.50, and 1.50 ≤ (R7+R8)/(R7-R8). 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.
