Abstract
According to an embodiment of the present invention, there is provided an aspherical mirror for focusing a laser beam in a linear pattern, the aspherical mirror including: a convex surface diffusely reflecting an irradiated laser beam; and a concave surface reflecting the laser beam such that the laser beam is focused at one point, wherein the laser beam reflected from the convex surface forms a long line beam as an angle of reflection with respect to a curvature of the convex surface changes, and the laser beam reflected from the concave surface is focused at one point on the line beam as an angle of reflection with respect to a curvature of the concave surface changes.
