Patent ID: 11803033

Abstract:
Disclosed is a camera optical lens, comprising, from an object side to an image side in sequence: a first lens having a negative refractive power; a second lens having a positive refractive power; a third lens having a negative refractive power; a fourth lens having a positive refractive power; and a fifth lens having a negative refractive power; the camera optical lens satisfies: −5.00≤f1/f≤−3.00; −1.50≤f5/f≤−1.00; 1.20≤(R7+R8)/(R7−R8)≤3.00; and 8.00≤d7/d8≤14.00; where, f denotes a focus length of the camera optical lens; f1 and f5 denotes focus length of the first and fifth lens respectively; R7 and R 8 denote central curvature radii of an object side surface and an image side surface of the fourth lens respectively; d7 denotes an on-axis thickness of the fourth lens; and d8 denotes an on-axis distance from the image side surface of the fourth lens to an object side surface of the fifth lens.
