Abstract:
In a method for the production of x-ray-optical gratings composed of a first material forming of periodically arranged grating webs and grating openings, a second material is applied by electroplating to fill the grid openings. The electroplating is continued until a cohesive layer of the second material with uniform height is created over the grating webs with this layer having a large absorption coefficient, the absorption properties of the grating structure of the grating are homogenized, so an improvement of the measurement signals that are generated with this grating is improved. Moreover, the mechanical stability of gratings produced in such a manner is improved.
