Abstract
A lens module includes a first lens, a second lens, and a third lens comprising a convex object-side surface and a convex image-side surface. The lens module also includes a fourth lens including a concave object-side surface and a concave image-side surface, a fifth lens including a concave object-side surface, and a sixth lens including an inflection point formed on an image-side surface thereof. The first to sixth lenses are sequentially disposed from an object side to an image side.
