Abstract:
An optical system includes a first lens having negative refractive power and having two concave surfaces, a second lens having positive refractive power, a third lens having refractive power, a fourth lens having refractive power, a fifth lens having refractive power, a sixth lens having refractive power, and a seventh lens having refractive power. The first to seventh lenses are sequentially disposed from an object side. Whereby an aberration improvement effect may be increased and high resolution and a wide angle may be implemented.

Claim (Index 1):
An optical system comprising:\n a first lens having negative refractive power and having two concave surfaces; a second lens having positive refractive power; a third lens having refractive power; a fourth lens having refractive power; a fifth lens having refractive power; a sixth lens having refractive power; and a seventh lens having refractive power, wherein the first to seventh lenses are sequentially disposed from an object side, and the seventh lens has at least one inflection point formed on at least one of an object-side surface and an image-side surface of the seventh lens.
