Title:
OPTICAL CAMERA LENS
Document Type and Number:
WIPO Patent Application WO/2022/047993
Kind Code:
A1
Abstract:
The present invention relates to the field of optical lenses, and an optical camera lens is disclosed. The optical camera lens sequentially comprises, from an object side to an image side, a first lens having a positive refractive power, a second lens having a positive refractive power and a third lens having a negative refractive power. The camera optical lens has an overall focal length f, the first lens has a focal length f1, the second lens has a focal length f2, the third lens has a focal length f3, an object side face of the third lens has a radius of curvature R5, an image side face of the third lens has a radius of curvature R6, the second lens has an on-axis thickness d3, the on-axis distance from an image side face of the second lens to the object side face of the third lens is d4, and the following relational expressions are met: 1.40 ≤ f1/f ≤ 2.00, 0.65 ≤ f2/f ≤ 0.90, -1.50 ≤ f3/f ≤ -0.85, 2.50 ≤ d3/d4 ≤ 10.00, and 2.00 ≤ (R5+R6)/(R5-R6) ≤ 4.5. The optical camera lens according to the present invention has a good optical properties, such as a large aperture, a wide angle and an ultra-thin thickness.
