Abstract

An optical lens assembly and an imaging device including the optical lens assembly are disclosed. The optical lens assembly may include, sequentially from an object side to an image side along an optical axis, a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens. The first lens may have a negative refractive power; the second lens may have a positive refractive power; the third lens may have a positive refractive power; the fourth lens may have a negative refractive power, an object-side surface thereof is a convex surface and an image-side surface thereof is a concave surface; the fifth lens may have a positive refractive power, and both of an object-side surface and an image-side surface thereof are convex surfaces; and the sixth lens may have a negative refractive power.
