Imaging lens system with wide field of view

Abstract

An imaging lens system is provided. The imaging lens system includes a first lens having refractive power, a second lens having refractive power, a third lens having a concave object-side surface, a fourth lens having refractive power, a fifth lens having refractive power, a sixth lens having a concave object-side surface, and a seventh lens having refractive power. The first to seventh lenses may be sequentially disposed from an object side to an imaging side. In the imaging lens system, 20<V1-V3 and 190°≤FOV, where V1 is an Abbe number of the first lens, V3 is an Abbe number of the third lens, and FOV is a field of view of the imaging lens system.
