Patent ID: 11543630

Abstract:
A camera optical lens includes first to fifth lenses. The camera optical lens satisfies: 1.50≤(R5+R6)/(R5−R6); 0.40≤d4/d6≤1.25; 1.00≤TTL/IH≤1.30; and 1.00≤(R3+R4)/(R3−R4)≤2.40, where R3 and R4 denote curvature radiuses of an object side surface and an image side surface of the second lens, respectively; R5 and R6 denote curvature radiuses of an object side surface and an image side surface of the third lens, respectively; d4 denotes an on-axis distance from the image side surface of the second lens to the object side surface of the third lens; d6 denotes an on-axis distance from the image side surface of the third lens to an object side surface of the fourth lens; IH denotes an image height of the camera optical lens; and TTL denotes a total optical length. The camera optical lens has good optical performance while satisfying design requirements for ultra-thin, wide-angle lenses having large apertures.
