Abstract

The influence of replication on the X-ray diffraction efficiency of blazed reflection gratings is studied by measurements at 0.834 and 1.334 nm. Full electromagnetic calculations show that the differences in the diffraction efficiency of the first generation replicas can be explained by rounding off of the tops of the grooves as measured by stylus measurements of the groove profiles. The efficiency degradation of the second generation replica can not easily be attributed to a different groove shape. The cause of this degradation is as yet unclear. The apex angle of a blazed X-ray grating is not a critical parameter for its efficiency.
