Abstract

A camera optical lens sequentially includes six lenses: six lenses from an object-side to an image-side: a first lens having negative refractive power, a second lens having positive refractive power, a third lens having positive refractive power, a fourth lens having negative refractive power, and a fifth lens having positive refractive power, and a sixth lens having negative refractive power. Following relational expressions are satisfied: 3.00≤(f5−f6)/f≤4.00; 2.00≤(d1+d3+d5)/(d2+d4)≤4.50; −1.30≤(R1+R2)/(R1−R2)≤−1.05. The camera optical lens according to the present disclosure has excellent optical characteristics of sufficient aberration correction, large aperture, wide-angle and ultra-thinness, and is particularly suitable for a mobile phone camera lens assembly and a WEB camera lens which are composed of camera elements such as CCD, CMOS with high resolution, and a vehicle-mounted lens.
