Abstract
Disclosed herein is an imaging lens suitable for a camera module using a high resolution imaging sensor, decreasing a flare phenomenon and reducing the sensitivity. The imaging lens comprises, orderly from the object side, a first lens having positive (+) refractive force; a second lens having negative (−) refractive force; a third lens having positive (+) refractive force; a fourth lens having positive (+) refractive force; and a fifth lens having negative (−) refractive force, wherein an object side plane of the third lens is convexly formed.
Claims18
An imaging lens system, comprising, in order from an object side to an image side:
- a first lens having positive (+) refractive power;
- a second lens;
- a third lens;
- a fourth lens having positive (+) refractive power;
- and
- a fifth lens having negative (−) refractive power,
- wherein the imaging lens meets a condition expression of 1.5<N1<1.6, and 1.5<N3<1.6, where N1 is a refractive index of the first lens, and N3 is a refractive index of the third lens.
A camera module comprising an imaging lens system and an image sensor, wherein the imaging lens system comprises, in order from an object side to an image side:
