| Summary: | An optical imaging system of the present invention comprises: a first lens having a positive refractive power; a second lens having a positive refractive power; a third lens having a positive refractive power; a fourth lens having a negative refractive power; a fifth lens which has a positive refractive power and is concave toward an object; and a sixth lens which has a negative refractive power and has an inflection point on an image side. The first lens to the sixth lens are sequentially arranged in a direction from the object side to the image plane. The present invention provides an optical imaging system having a high resolution.
