The invention discloses a near-infrared zoom lens with an embedded liquid lens assembly. The lens includes a lens barrel, lens bodies, a diaphragm, the liquid lens assembly and an optical filter; thelens bodies comprise the first lens body, the second lens body, the third lens body and the fourth lens body, wherein the first lens body, the second lens body, the third lens body, the diaphragm, theliquid lens assembly, the fourth lens and the optical filter are arrayed sequentially from an object side to an image side in the lens barrel; a double-convex glass spherical-surface lens body with positive focal power is adopted as the first lens body, a falcate glass spherical-surface lens with positive focal power is adopted as the second lens body, a double-concave glass spherical-surface lens with negative focal power is adopted as the third lens body, and a double-convex glass spherical-surface lens body with positive optical power is adopted as the fourth lens body. According to the lens, the four glass spherical-surface lens bodies and the liquid lens assembly are added, so that the problems are solved that the working distance range of traditional fixed-focus lenses is narrow, the number of existing zoom lenses in which liquid lens assemblies are embedded is large, and the definition is low.
