Abstract
A lens module includes: a first lens having negative refractive power; a second lens having positive refractive power; a third lens having negative refractive power; a fourth lens having negative refractive power; a fifth lens of which an object-side surface is concave; and a sixth lens having one or more inflection points on an image-side surface thereof, wherein the first to sixth lenses are sequentially disposed from an object side of the lens module to an image side of the lens module.
Claims8
A lens module comprising:
- a first lens having negative refractive power and a concave object-side surface;
- a second lens having a refractive power;
- a third lens having a refractive power;
- a fourth lens having negative refractive power and a convex object-side surface in a paraxial region thereof;
- a fifth lens having a refractive power and a concave object-side surface in a paraxial region thereof;
- and
- a sixth lens having a refractive power and a convex object-side surface in a paraxial region thereof,
- wherein the lens module includes a total of six lenses and the first to sixth lenses are sequentially disposed from an object side of the lens module to an image side of the lens module, and
- wherein 0.6<f5/f, where f5 is a focal length of the fifth lens and f is an overall focal length of the lens module.
