Patent ID: 11262549

Abstract:
The present disclosure relates to the technical field of 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≤n3≤2.20, −2.00≤f3/f4≤2.00, −10.00≤(R13+R14)/(R13−R14)≤10.00 and 1.70≤n6≤2.20, where f denotes a focal length of the camera optical lens; f1 denotes a focal length of the first lens; f3 denotes a focal length of the third lens; f4 denotes a focal length of the fourth lens; n3 denotes a refractive index of the third lens; n7 denotes a refractive index of the seventh lens; R13 denotes a curvature radius of an object-side surface of the seventh lens; and R14 denotes a curvature radius of an image-side surface of the seventh lens.
