Abstract
A lens module include: a first lens having positive refractive power; a second lens having positive refractive power; a third lens having refractive power; a fourth lens having positive refractive power; a fifth lens having refractive power; and a sixth lens having negative refractive power and having an inflection point formed on an image-side surface thereof. The lens module may satisfy the following Conditional expressions: 0.36<SD/f<0.48, where SD is a size of a stop opening and f is an overall focal length of the lens module.
