Camera optical lens including seven lenses of ++−+−+−, ++−+++− or ++−−−+− refractive powers
The present disclosure relates to an optical lens and discloses a camera optical lens. The 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, a sixth lens and a seventh lens. The camera optical lens satisfies following conditions: 1.51≤f1/f≤2.50; 1.70≤n1≤2.20; −2.00≤f3/f4≤2.00; 2.50≤(R13+R14)/(R13−R14)≤10.01; and 1.70≤n7≤2.20; where f, f1, f3 f4 denote a focal length of the camera optical lens, a focal length of the first lens, a focal length of the third lens, a focal length of the fourth lens respectively; n2 denotes a refractive index of the second lens; n7 denotes a refractive index of the seventh lens; R13 and R14 denote a curvature radius of an object-side surface and a curvature radius of an image-side surface of the seventh lens respectively.
