Title:
CAMERA OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2022/041383
Kind Code:
A1
Abstract:
The present invention provides a camera optical lens. The camera optical lens comprises five lenses, which are sequentially as follows from an object side to an image side: a first lens having a positive refractive power, a second lens having a negative refractive power; a third lens having a positive refractive power, a fourth lens having a positive refractive power, and a fifth lens having a negative refractive power, wherein the focal length of the overall optical camera lens is f, the focal length of the second lens is f2, the axial distance from the image-side surface of the first lens to the object-side surface of the second lens is d2, the axial distance from the image-side surface of the second lens to the object-side surface of the third lens is d4, the center curvature radius of the object-side surface of the fourth lens is R7, the center curvature radius of the image-side surface of the fourth lens is R8, and the following relational expressions are satisfied: -6.00≤f2/f≤-3.00; -20.00≤(R7+R8)/(R7-R8)≤-2.00; 1.60≤d2/d4≤6.00. The camera optical lens has good optical performance and also satisfies design requirements of a wide angle and ultra-thinness.
