Abstract
An optical lens includes a first lens, a second lens, a third lens, a fourth lens and a fifth lens arranged sequentially along an optical axis from an magnified side to a minified side. A center thickness of the first lens is TH, a center thickness of the second lens is TH, a center thickness of the third lens is TH, a center thickness of the fourth lens is TH, a center thickness of the fifth lens is TH, and an effective focal length of the optical lens is EFL, wherein the optical lens fits at least one of the following conditions: (1) 0.52<(TH+TH+TH)/EFL<1.0; (2) 0.5<(TH+TH+TH)/EFL<0.65; and (3) (TH+TH+TH)/(TH+TH+TH)>1.20. The optical lens can reduce aberration and has high resolution.
