Method of fabricating cylindrical gratings
Abstract
A method to improve dimension accuracy of grating elements in the fabrication of metallic cylinders is described. The fabrication method produces cylindrical gratings with rectangular closed holes. The accuracy improves the dimensions of the grating element and their purity. The method provides a more compact abutement of the alloy to the surface and holder. Prior to filling the gap the grating is heated to the melting point of the alloy.
