Abstract

The process to manufacturing free-standing diffracting transmission gratings with high ruling density and high efficiency is described. This process has been developed at the Dr. Johannes-Heidenhain GmbH in cooperation with the Max-Planck-Institut. Two steps are involved, the mechanical ruling of the original master and the photomechanical replication of the in dividual grating facets. At present gratings of up to 2000 l/mm are available. Measured X-ray efficiencies are close to the theoretically expected values.
