Abstract
The present invention relates to an optical system. An optical system of the present invention includes, sequentially from an object side, a first lens having a positive refractive power and an object-side surface convex toward the object side; a second lens having a negative refractive power; a third lens having a negative refractive power; a fourth lens having a positive refractive power, a fifth lens having a negative refractive power and an image-side surface convex toward an image side; and a sixth lens having a negative refractive power and an image-side surface concave toward the image side.
