Abstract
There is provided a lens module including: a first lens having positive refractive power; a second lens having refractive power, an image-side surface thereof being concave; a third lens having positive refractive power; a fourth lens having negative refractive power, an object-side surface thereof being convex; and a fifth lens having refractive power and having one or more inflection point formed on at least one of an object-side surface and an image-side surface thereof, wherein the first, second, third, fourth and fifth lenses are disposed in a sequential order from the first lens to the fifth lens.
Claims25
A lens module comprising:
- a first lens having positive refractive power;
- a second lens having refractive power, an image-side surface thereof being concave;
- a third lens having positive refractive power of which an object-side surface is convex;
- a fourth lens having negative refractive power, an object-side surface thereof being convex;
- and
- a fifth lens having negative refractive power and having one or more inflection point formed on at least one of an object-side surface and an image-side surface thereof
- wherein the first, second, third, fourth and fifth lenses are disposed in a sequential order from the first lens to the fifth lens.
A lens module comprising:
- a first lens having positive refractive power;
- a second lens having refractive power;
- a third lens having positive refractive power of which an object-side surface is convex;
- a fourth lens having refractive power, an image-side surface thereof being concave;
- and
- a fifth lens having negative power and having one or more inflection point formed on at least one of an object-side surface and an image-side surface thereof,
- wherein the lens module satisfies the following Conditional Expressions:
- 1.0<r7/r8<1.6 [Conditional Expressions]
- where r7 is a radius of curvature of an object-side surface of the fourth lens, and r8 is a radius of curvature of the image-side surface of the fourth lens.
