Abstract

The present disclosure relates to the field of optical lenses, and discloses a camera optical lens. The camera optical lens sequentially includes seven lenses from an object-side surface to an image side: a first lens having positive refractive power, a second lens having negative refractive power, a third lens having negative refractive power, a fourth lens having positive refractive power, a fifth lens having negative refractive power, a sixth lens having positive refractive power, and a seventh lens having negative refractive power; and the following relational expressions are satisfied: 0.20≤H0.6r9/IH≤0.30; 16.00≤f1/H0.6r1*tan(semi-FOV)≤30.00; −6.00≤(H0.6r14/d13)*(f7/f)≤−3.00. The camera optical lens has excellent imaging performance, meets the design requirements of wide-angle, low sensitivity, good processability, miniaturization and sufficient correction of aberration, and is particularly suitable for a mobile phone camera lens assembly composed of camera elements such as CCD CMOS with high definition, a WEB camera lens assembly and a vehicle-mounted lens assembly.
