Abstract
The present disclosure relates to the field of optical lenses and provides a camera optical lens. The camera optical lens includes, from an object side to an image side: a first lens; a second lens; a third lens; a fourth lens; a fifth lens; a sixth lens; and a seventh lens. The camera optical lens satisfies following conditions: 1.51≤f1/f≤2.50, 1.70≤n1≤2.20, −2.00≤f3/f4≤0.00; 3.00≤(R13+R14)/(R13−R14)≤10.00; and 1.70≤n2≤2.20. The camera optical lens can achieve a high imaging performance while obtaining a low TTL.
