A new configuration of diffractive-refractive optics for beam splitting is investigated. The set-up can be applied to perform imaging with two beams simultaneously. It brings advantages toward dynamic studies using image guided diffraction or fluorescence spectroscopy. The optimal energy range of operation for the beam-splitter is between 7keV and 24 keV, reaching best efficiency at an energy of 10keV. Due to the long focusing distances(several tens of meters) created by the diffractive–refractive optics and the higher refraction efficiency in the soft erenergy range, the presented set-ups are ideal for hard X-ray FELsources.
