Patent ID: 11314049

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: an aperture; 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 having a positive refractive power; a fifth lens having a negative 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: 1.68≤n2≤2.20; and 15.00≤f3/f, where f denotes a focal length of the camera optical lens; n2 denotes a refractive index of the second lens; and f3 denotes a focal length of the third lens.
