Abstract
An optical lens assembly. The optical lens assembly comprises a lens barrel, and first to sixth lenses. The refractive power of the fifth lens and the refractive power of the sixth lens are positive-negative opposite, and an image-side surface of the fifth lens is a convex surface. The lens barrel further comprises a fourth spacer and a fifth spacer, the fourth spacer being disposed between the fourth lens and the fifth lens, and the fifth spacer being disposed between the fifth lens and the sixth lens. An axial distance EP45 from an image-side surface of the fourth spacer to an object-side surface of the fifth spacer, a center thickness CT5 of the fifth lens, an effective focal length f5 of the fifth lens, an effective focal length f6 of the sixth lens and a radius of curvature R10 of the image-side surface of the fifth lens satisfy: −0.5<EP45/CT5*|f5+f6|/R10<0.
