An optical imaging system includes a first lens having positive refractive power and having a convex object-side surface; a second lens having negative refractive power; a third lens having refractive power; a fourth lens having refractive power; a fifth lens having refractive power; a sixth lens having positive refractive power and having a convex image-side surface; and a seventh lens having negative refractive power and having a concave image-side surface, and the first to seventh lenses are disposed in order from an object side. In the optical imaging system, 1<f/f6 and V2<40, where f is a focal length of the optical imaging system, f6 is a focal length of the sixth lens, and V2 is an Abbe number of the second lens.

Optical imaging system

A lens module includes a first lens, a second lens, and a third lens comprising a convex object-side surface and a convex image-side surface. The lens module also includes a fourth lens including a concave object-side surface and a concave image-side surface, a fifth lens including a concave object-side surface, and a sixth lens including an inflection point formed on an image-side surface thereof. The first to sixth lenses are sequentially disposed from an object side to an image side.

Lens module

An optical 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 an object-side surface that is convex with a meniscus shape. The second lens includes an image-side surface that is convex. The third lens includes an image-side surface that is concave. The fifth lens includes an image-side surface that is concave. The first to sixth lenses are sequentially disposed from an object side to an image side.

Optical system

An optical imaging system includes a first lens having positive refractive power and having a convex object-side surface; a second lens having negative refractive power; a third lens having refractive power; a fourth lens having refractive power; a fifth lens having refractive power; a sixth lens having positive refractive power and having a convex image-side surface; and a seventh lens having negative refractive power and having a concave image-side surface, and the first to seventh lenses are disposed in order from an object side. In the optical imaging system, 1&#x3c;f/f6 and V2&#x3c;40, where f is a focal length of the optical imaging system, f6 is a focal length of the sixth lens, and V2 is an Abbe number of the second lens.

Disclosed herein is an imaging lens unit, including: a first lens having a positive (+) power; a second lens having a negative (&#x2212;) power; a third lens selectively having one of a positive (+) and negative (&#x2212;) power; a fourth lens having a negative (&#x2212;) power; and a fifth lens having a negative (&#x2212;) power, wherein the first lens, the second lens, the third lens, the fourth lens, and fifth lens are arranged in order from an object to be formed as an image, and the fourth lens is concave toward an image side.
