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/° C.) of 3 or greater.

Imaging lens system

An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens. The first lens has a negative refractive power. The second lens has a negative refractive power. The third lens has a positive refractive power. The fourth lens has a positive refractive and an object-side surface that is concave in a paraxial region thereof. The fifth lens has a positive refractive power. The sixth lens has a negative refractive power. The first to sixth lenses are sequentially disposed in ascending numerical order from an object side of the optical imaging system toward an imaging plane of the optical imaging system. Two lenses that are adjacent to each other among the first to sixth lenses are cemented to each other to form a cemented lens.

Optical imaging system

An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens. The first lens includes a negative refractive power, and the second lens includes a negative refractive power. The third lens includes a positive refractive power, and the fourth lens includes a positive refractive power, an object-side surface thereof being concave. The fifth lens includes a positive refractive power. The sixth lens includes a negative refractive power. The first to sixth lenses are sequentially disposed from an object side toward an imaging plane. One lens of the first to sixth lenses is cemented to a lens adjacent thereto.

An optical imaging system includes a first lens having refractive power; a second lens having refractive power; a third lens having refractive power and cemented to the second lens; a fourth lens having refractive power; a fifth lens having refractive power and cemented to the fourth lens; a sixth lens having refractive power; a seventh lens having refractive power; and an eighth lens having refractive power. The first to eighth lenses are sequentially disposed in numerical order beginning with the first lens from an object side of the optical imaging system toward an imaging plane of the optical imaging system.
