Abstract

A camera optical lens includes: first lens, second lens and third lens. Focal length f of camera optical lens, focal length f1 of first lens, on-axis distance d2 from image-side surface of the first lens to object-side surface of the second lens, total optical length TTL, field of view FOV of camera optical lens, full field image height IH of camera optical lens, curvature radius R5 of object-side surface of third lens, curvature radius R6 of image-side surface of third lens, refractive index n1 of first lens satisfy following relational expressions: 0.80≤f1/f≤1.60; 0.14≤d2/TTL≤0.22; 100.00≤(FOV*f)/IH≤115.00; 1.40≤R5/R6≤4.00; and 1.70≤n1≤2.10. The camera optical lens has low sensitivity and capability of achieving medium- to long-range distance imaging while having good optical performance.
