Abstract
An optical lens assembly, including: a lens barrel; five lenses arranged sequentially along optical axis; a first spacer, in contact with at least part of an image-side surface of a first lens; a second spacer, in contact with at least part of an image-side surface of the second lens; and a focal length f2 of the second lens, the center thickness CT2 of the second lens on the optical axis, an air spacing T23 between the second lens and a third lens on the optical axis, a maximum thickness CP2 of the second spacer, and a distance EP12 between an image-side surface of the first spacer and an object-side surface of the second spacer along the optical axis satisfy: −50.0<f2/(CT2+T23)+f2/(EP12+CP2)<0.
