An in‐line monochromatization scheme suitable for 10–40 keV synchrotron radiation is presented based on the use of six crystal reflections that achieves meV and sub‐meV bandwidths with high efficiency. The theoretical spectral efficiency surpasses all previous multicrystal designs and approaches that of single room‐temperature back‐reflecting crystals. This article presents the designs of two such devices along with their theoretical and measured performances.
