Camera optical lens

Abstract

Provided is a camera optical lens, which includes first to fourth lenses. The camera optical lens satisfies: 0.03≤R1/R2≤0.10; 1.00≤R3/R4≤1.50; 3.50≤R5/R6≤5.50; and 3.50≤d1/d2≤5.50, where R1 and R2 denote curvature radiuses of an object side surface and an image side surface of the first lens, respectively; 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; d1 denotes an on-axis thickness of the first lens; and d2 denotes an on-axis distance from the image side surface of the first lens to the object side surface of the second lens. The camera optical lens has good optical performance while satisfying design requirements for ultra-thin, wide-angle lenses having large apertures.
