Patent ID: 11835688

Abstract:
A camera optical lens includes, from an object side to an image side: a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens. The camera optical lens satisfies conditions of −4.00≤f2/f≤−1.50, −10.00≤f4/f5≤−2.00, −20.00≤(R5+R6)/(R5−R6)≤−2.00, R10/R9≤−3.00, and 2.00≤d1/d2≤7.00. Here f denotes a focal length of the camera optical lens, f2 denotes a focal length of the second lens, f4 denotes a focal length of the fourth lens, f5 denotes a focal length of the fifth lens, R5 denotes a curvature radius of an object-side surface of the third lens, R6 denotes a curvature radius of an image-side surface of the third lens, R9 denotes an curvature radius of an object-side surface of the fifth lens. The camera optical lens of the present disclosure has excellent optical performances, and meanwhile can meet design requirements of a large aperture, a wide angle and ultra-thin.
