Abstract
A camera optical lens is provided, including from an object side to an image side: a first lens having positive refractive power; a second lens having positive refractive power; and a third lens having negative refractive power, wherein the camera optical lens satisfies following conditions: 1.40≤f1/f≤2.00; 0.65≤f2/f≤0.90; −1.50≤f3/f≤−0.85; 2.50≤d3/d4≤10.00; and 2.00≤(R5+R6)/(R−R6)≤4.50. The above camera optical lens can meet design requirements for large aperture, wide angle and ultra-thinness while maintaining good imaging quality.
