Abstract
A lens module includes a first lens having refractive power, a second lens having refractive power, a third lens having refractive power, a fourth lens having refractive power, a fifth lens having refractive power and having a concave object-side surface and a concave image-side surface, and a sixth lens having refractive power and a concave image-side surface. The first to sixth lenses are sequentially disposed from an object side to an image side.
Claims15
A lens module comprising:
- a first lens having positive refractive power, a convex object-side surface, and a concave image-side surface;
- a second lens having negative refractive power, a convex object-side surface, and a concave image-side surface;
- a third lens having a convex object-side surface;
- a fourth lens having a refractive power;
- a fifth lens having a concave image-side surface in the optical axis portion, wherein the optical axis portion excludes a peripheral region;
- and
- a sixth lens having positive refractive power in the optical axis portion, and a concave image-side surface in the optical axis portion,
- wherein the first to sixth lenses are sequentially disposed from an object side to an image side, and
- wherein 0<r3/f<10.0
- where f is an overall focal length of the lens module, and r3 is a radius of curvature of an image-side surface of the first lens.
