PURPOSE:To improve the quality of the machining by using a linear light spot obtained by condensing partial light with an uniform intensity distribution extracted from laser light to perform the machining and reducing the variance of the quality of the machining by a machining part. CONSTITUTION:The cylindrical laser light 14 obtained through a concave lens 12 and a convex lens 13 is formed to the light 18 with the uniform intensity through a field diaphragm 16. The light 18 with the uniform intensity is passed through a cylindrical lens 19 and the linear light spot 20 is obtained. The linear light spot 20 is projected on a reed 9 mounted on an XY table 6 to perform the soldering. The uniform machining can be performed by this constitution. |
