Abstract
Disclosed is a camera optical lens. The camera optical lens includes from an object side to an image side in sequence: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, and an eighth lens. The camera optical lens satisfies the following conditions: 1.00≤d3/d1≤3.00; 0.20≤R3/R4≤0.90; 1.00≤f4/f3≤4.00; 0.50≤f6/f7≤1.40; 1.80≤nd8≤2.20. The thicknesses on-axis of the first lens and the second lens are d1 and d3, respectively. The curvature radius of the object side surface and image side surface of the second lens are R3 and R4, respectively. The focal lengths of the third lens, the fourth lens, the sixth lens, and the seventh lens are f3, f4, f6, and f7, respectively. The refractive index of the eighth lens is nd8. The camera optical lens has good optical performance and is characterized by a large aperture and miniaturization.
