Patent ID: 11966027

Abstract:
Disclosed is a camera optical lens. including, nine lenses from an object side to an image side being: a first lens with a negative refractive power, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens all with a positive refractive power, a seventh lens with a negative refractive power, an eighth lens with a positive refractive power and an ninth lens with a negative refractive power. The camera optical lens satisfies: −1.60≤f1/f≤−0.50, 2.50≤d3/d4≤10.00; wherein, f denotes a focal length of the camera optical lens, f1 denotes a focal length of the first lens, d3 denotes an on-axis thickness of the second lens, and d4 denotes an on-axis distance from the second lens to the third lens. The camera optical lens has good optical performance, and meets the design requirements of wide-angle and ultra-thin.
