Abstract
An imaging lens system includes a first lens, a second lens, a third lens having negative refractive power, a fourth lens, a fifth lens, and a sixth lens, disposed in order from an object side in a direction of an imaging plane, wherein one or more of the first to sixth lenses has a refractive index of 1.8 or greater, and has a refractive index temperature coefficient (10−6/° C.) of 3 or greater.
Claims12
An imaging lens system, comprising:
- a first lens having a convex object-side surface in a paraxial region;
- a second lens having negative refractive power;
- a third lens having a refractive power;
- a fourth lens having positive refractive power;
- a fifth lens having a refractive power;
- a sixth lens having a refractive power;
- and
- a seventh lens having a refractive power,
- wherein the first to seventh lenses are sequentially disposed in order from an object side toward an imaging plane,
- wherein the imaging lens system has a total number of seven lenses with refractive power, and
- wherein a thickness of the first lens along an optical axis is greater than a thickness of the fifth lens along the optical axis.
