Patent ID: 11209628

Abstract:
The present disclosure relates to optical lens, comprising from an object side to an image side in sequence: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens; the camera optical lens satisfies following conditions: 1.00≤f1/f≤1.50; 1.70≤n4≤2.20; −2.00≤f3/f4≤2.00; 0.50≤(R13+R14)/(R13−R14)≤10.00; and 1.70≤n7≤2.20; where, f denotes a focus length of the camera optical lens; f1, f3 and f4 denote focus lengths of the first lens, the third lens and the fourth length respectively; n4 denotes a refractive index of the fourth lens; n7 denotes a refractive index of the seventh lens; R13 and R14 denote curvature radiuses of an object side surface and an image side surface of the seventh lens, respectively.
