US Patent 11428905 Camera optical lens

The present disclosure relates to the technical field of optical lens and discloses 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 positive refractive power, a fourth lens, a fifth lens having a positive refractive power, a sixth lens having a positive refractive power, and a seventh lens having a negative refractive power. The camera optical lens satisfies following conditions: 1.70>f6/f≤5.00; −4.00≤R14/R13≤−1.00; −5.00≤f2/f≤−2.00; 1.00≤d8/d9≤2.00. The camera optical lens can achieve excellent optical characteristics with a large aperture, wide-angle, and being ultra-thin.
