Patent attributes
A camera optical lens includes a first lens having a positive refractive power, a second lens having a refractive power, a third lens having a negative refractive power, a fourth lens having a positive refractive power, and a fifth lens having a negative refractive power, which are sequentially arranged from an object side to an image side. 0.90≤f1/f≤1.20, 5.00≤(R3+R4)/(R3−R4)≤30.00, 3.00≤d5/d6≤10.00, and −15.00≤(R5+R6)/(R5−R6)≤−3.00. f denotes a focal length of the camera optical lens, f1 denotes a focal length of the first lens, R3 denotes a curvature radius of an object-side surface of the second lens, R4 denotes a curvature radius of an image-side surface of the second lens, and R5 denotes a curvature radius of an object-side surface of the third lens. The camera optical lens has good optical performance and meets the design requirements of a large aperture, a wide angle, and ultra-thinness.
