Abstract
A camera optical lens includes six-piece lenses, from an object side to an image side, the six-piece lenses are: a first lens having a positive refractive power, a second lens having a negative refractive power, a third lens having a negative refractive power, a fourth lens, a fifth lens having a positive refractive power and a sixth lens having a negative refractive power. The camera optical lens satisfies conditions of 0.65≤f1/f≤0.85, 0.80≤d3/d4≤1.20, 0.85≤d8/d9≤1.35, and −4.00≤R9/R10≤−2.00. Here 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. The camera optical lens of the present disclosure has excellent optical performances, and meanwhile can meet design requirements of ultra-thin and a wide angle.
