Patent ID: 11262555

Abstract:
Provided is a camera optical lens including, sequentially from an object side to an image side, first to seventh lenses. The camera optical lens satisfies following conditions: 20.00≤R7/d7≤30.00; 20.00≤v7−v5≤30.00; and −12.00≤(R1−R2)/(R3−R4)≤−1.00, where v5 denotes an abbe number of the fifth lens; v7 denotes an abbe number of the seventh lens; R1 denotes a curvature radius of an object side surface of the first lens; R2 denotes a curvature radius of an image side surface of the first lens; R3 denotes a curvature radius of an object side surface of the second lens; R4 denotes a curvature radius of an image side surface of the second lens; R7 denotes a curvature radius of an object side surface of the fourth lens; and d7 denotes an on-axis thickness of the fourth lens. The camera optical lens can achieve high optical performance such as large-aperture, wide-angle and ultra-thin.
