Optical lens assembly and imaging device

Abstract

An optical lens assembly and an imaging device including the optical lens assembly are disclosed. The optical lens assembly, from an object side to an image side along an optical axis may sequentially include: a first lens, a second lens, a third lens, a fourth lens and a fifth lens. The first lens is of meniscus shape, at least one of surfaces of the second lens is a convex surface, one of the third and fourth lens has a positive refractive power, and the other has a negative refractive power, wherein the third lens and the fourth lens are cemented to form an cemented lens, at least one of surfaces of the fifth lens is a concave surface, and at least one of the first lens, second lens or the fifth lens has a positive refractive power.

Dependencies are inferred from the claim text.
