A new method of harmonics separation for an X-ray crystal monochromator is proposed. The method is based on diffractive–refractive optics.

X-ray collimation as a novel application of diffractive–refractive optics was studied theoretically and experimentally. A set-up with two crystals in a dispersive arrangement successfully demonstrated X-ray collimation in the energy range 6.3–18.8 keV.
