Zusammenfassung:	PURPOSE:To provide the mirror capable of condensing a laser beam to a straight form and arbitrarily setting the length of the straight line of the condensed part and focal length. CONSTITUTION:A reflection surface 1 is formed of an aspherical curved face 2. The surface shape in a direction (a)-(a) of this curved surface 2 is formed as a parabola having a focus at a first axis 4 and the surface shape in a direction (b)-(b) is formed as a round shape around a second axis 5 so that the incident laser beam is separated and condensed to the first and second axes 4, 5. The focal length and the length of the straight line of the condensed light are changed by changing the equation of the parabola and the rotating radius with the second axis 5.
