Abstract:
Provided is a camera optical lens, including first to fifth lenses. The camera optical lens satisfies: −3.50≤f2/f≤−1.50; 10.00≤d1/d2≤35.00; 1.80≤(R5+R6)/(R5−R6)≤8.00; R9/d9≤−15.00; and −30.00≤R2/R1≤−10.00, where f denotes a focal length of the camera optical lens; f2 denotes a focal length of the second lens; d1 denotes an on-axis thickness of the first lens; d2 denotes an on-axis distance from an image side surface of the first lens to an object side surface of the second lens; R5 and R6 denote curvature radiuses of an object side surface and an image side surface of the third lens, respectively; d9 denotes an on-axis thickness of the fifth lens; and R1 and R2 denote curvature radiuses of an object side surface and the image side surface of the first lens. The camera optical lens has good optical performance and satisfies the requirement for ultra-thin design.
