Patent ID: 11698511

Abstract:
Provided is a camera optical lens including, sequentially from an object side to an image side: a first lens having a negative refractive power; a second lens having a refractive power; a third lens having a positive refractive power; a fourth lens having a negative refractive power; a fifth lens having a refractive power; a sixth lens having a positive refractive power; and a seventh lens having a negative refractive power. At least one of the first to seventh lenses comprises a free-form surface. The camera optical lens satisfies following conditions: −3.00≤f4/f3≤−1.00; 2.90≤d9/d10≤8.50; and 2.00≤d11/d12≤15.00. The camera optical lens can achieve high optical performance while satisfying design requirements for ultra-thin, wide-angle lenses.
