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 having a positive refractive power, a second lens having a negative refractive power, a third lens having a negative refractive power, a fourth lens, a fifth lens and a sixth lens. The camera optical lens satisfies following conditions: 2.00R3/R45.00; 1.50R1/d13.00; 0.30R2/R32.00; and 1.02n2/n31.20. The camera optical lens can achieve a high imaging performance while obtaining a low TTL.
