Patent ID: 11513322

Abstract:
Provided is a camera optical lens, which 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 having a negative refractive power; a fifth lens having a negative refractive power; a sixth lens having a negative refractive power; a seventh lens having a positive refractive power; and an eighth lens having a negative refractive power. The camera optical lens satisfies following conditions: 3.50≤f1/f≤6.50; f2≤0.00; and 1.55≤n5≤1.70, where f denotes a focal length of the camera optical lens; f1 denotes a focal length of the first lens; f2 denotes a focal length of the second lens; and n5 denotes a refractive index of the fifth lens. The present disclosure can achieve high optical performance while achieving ultra-thin, wide-angle lenses having a big aperture.
