Therefore, it is an object of the present invention to provide a laser scanning system formed by injection molding first and second scanning lenses by using a plastic substance for excellently correcting field curvature at a scanned surface, minimizing focus shift and eccentricity caused by a temperature variation and {HEAD ~ degradation} of {TAIL ~ optical performance} due to a tilt error, and a relatively simplified lens shape while facilitating mold processing and injection molding
