Patent ID: 11733480

Abstract:
A camera optical lens includes first to fifth lenses. The camera optical lens satisfies: 0.75≤f1/f≤0.95; −4.50≤f3/f≤−3.00; 2.00≤(R5+R6)/(R5−R6)≤8.00; 3.00≤d7/d5≤5.00; and −12.00≤R3/R4≤−2.50, where f denotes a focal length of the camera optical lens; f1 denotes a focal length of the first lens; f3 denotes a focal length of the third lens; R3 and R4 respectively denote curvature radiuses of an object side surface and an image side surface of the second lens; R5 and R6 respectively denote curvature radiuses of an object side surface and an image side surface of the third lens; and d5 and d7 respectively denote an on-axis thickness of the third lens and an on-axis thickness of the fourth lens. The camera optical lens can achieve good optical performance while satisfying design requirements for ultra-thin, wide-angle lenses having large apertures.
