Abstract
The present disclosure relates to the field of optical lenses, and more specifically to a camera optical lens. The camera optical lens includes five lenses, which include, from an object side to an image side in sequence: 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 having a positive refractive power, and a fifth lens having a negative refractive power. The camera optical lens satisfies following relationships: 0.2 ≤ d 6 / TTL ≤ 0.36 ; 6. ≤ ( f 4 - f 5 ) / f 1 ≤ 10.1 ; - 1. ≤ ( R 5 + R 6 ) / ( R 5 - R 6 ) ≤ - 0.7 ; and - 0.8 ≤ ( R 9 + R 10 ) / f ≤ - 0.39 .
