We report on tests of a horizontally focusing germanium analyser, developed for thermal and hot neutron three-axis spectrometers at the ILL. The present version uses a slightly asymmetric 311 reflection (d.sup.hkl=1.706 A) from a pack of elastically bent perfect Ge crystals, whose bending radius canbe varied continuously to optimise the horizontal focusing. The performance of the new analyser compares favourably withthat of a Cu 200 (d.sup.hkl=1.807 A) device of the same dimensions.
