Abstract
The present invention relates to an imaging lens, the imaging lens including , in an ordered way from an object side, a first lens having positive (+) refractive power, a second lens having negative (−) refractive power, a third lens having positive (+) refractive power, a fourth lens having positive (+) refractive power, and a fifth lens having negative (−) refractive power, wherein an aperture is interposed between the first and second lenses, and the imaging lens meets a conditional expression of 20<V2<30 and 50<V3,V4,V5<60, where Abbe' number of second lens is V2, Abbe's number of third lens is V3, Abbe's number of fourth lens is V4, and Abbe's number of fifth lens is V5.
Claims7
An imaging lens, the imaging lens comprising, in an ordered way from an object side:
- a first lens having positive (+) refractive power;
- a second lens having negative (−) refractive power;
- a third lens having positive (+) refractive power and having an image side surface taking a convexly formed meniscus shape;
- a fourth lens having positive (+) refractive power and having an image side surface taking a convexly formed meniscus shape;
- and
- fifth lens having negative (−) refractive power,
- wherein the fifth lens is convexly formed at an object side surface, and the imaging lens meets a conditional expression of 20<V2<30 and 50<(V3,V4,V5)<60, where Abbe's number of the second lens is V2, Abbe's number of the third lens is V3, Abbe's number of the fourth lens is V4, and Abbe's number of the fifth lens is V5.
