An optical system for taking image comprises three lens elements with refractive power, wherein a first lens element with positive refractive power includes at least one aspheric surface, a second lens element with negative refractive power, and a third lens element with negative refractive power includes at least one aspheric surface, which are mounted orderly from the object side to the image side. By such arrangements, the volume of the lens assembly can be reduced, and can obtain high resolution.
