As a small spot x-ray monochromator, the XR5 is said to provide better energy resolution than those operating only in the large spot mode.
Very recently ultra-high resolution X-ray monochromators have been developed to provide sufficient flux in a narrow band width (5 meV at 14.4 ke V) in order to enable spectroscopy of nuclear energy levels (Mossbauer).
