Abstract
A lens module includes a first lens, an object-side surface thereof being convex; a second lens, both surfaces thereof being convex; a third lens, both surfaces thereof being concave; a fourth lens having negative refractive power, both surfaces thereof being convex; a fifth lens, an object-side surface thereof being concave; and a sixth lens, an object-side surface thereof being convex. The first to sixth lenses are sequentially disposed in numerical order from the first lens to the sixth lens from an object side of the lens module toward an image side of the lens module.
