Title:
CAMERA OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2022/047992
Kind Code:
A1
Abstract:
A camera optical lens (10), sequentially comprising, from an object side to an image side: a first lens (L1) having positive refractive power, a second lens (L2) having negative refractive power, a third lens (L3) having negative refractive power, a fourth lens (L4) having positive refractive power, and a fifth lens (L5) having negative refractive power. f denotes a focal length of the camera optical lens (10); f2 denotes a focal length of the second lens (L2); R1 denotes a curvature radius of an object side surface of the first lens (L1); R2 denotes a curvature radius of an image side surface of the first lens (L1); R7 denotes a curvature radius of an object side surface of the fourth lens (L4); R8 denotes a curvature radius of an image side surface of the fourth lens (L4); d5 denotes an on-axis thickness of the third lens (L3); d6 denotes an on-axis distance from an image side surface of the third lens (L3) to an object side surface of the fourth lens (L4). The camera optical lens (10) satisfies following conditions: -5.00≤f2/f≤-2.50; 2.00≤d5/d6≤4.00; -4.00≤R7/R8≤-1.30; -2.00≤(R1+R2)/(R1-R2)≤-1.00. The camera optical lens (10) has good optical performance while satisfying design requirements for ultra-thin, wide-angle lenses having large apertures.
