Abstract
The present disclosure relates to the field of optical lenses and provides 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; a sixth lens; the camera optical lens satisfies following conditions: 0.5≤f1/f≤10, 1.7≤n3≤2.2, and 0.01≤d5/TTL≤0.2, Fno≤2.06; where f denotes a focal length of the camera optical lens; f1 denotes a focal length of the first lens; n3 denotes a refractive index of the third lens, and d5 denotes a thickness on-axis of the third lens, Fno denotes an aperture F number of the camera optical lens, TTL denotes a total optical length of the camera optical lens. The present disclosure can achieve high optical performance while achieving ultra-thin, wide-angle lenses having a big aperture.
