PCT No. PCT/AU94/00480 Sec. 371 Date Feb. 15, 1996 Sec. 102(e) Date Feb. 15, 1996 PCT Filed Aug. 16, 1994 PCT Pub. No. WO95/05725 PCT Pub. Date Feb. 23, 1995An x-ray or neutron optic configuration includes a plurality of single crystal portions (25) formed with respective spaced x-ray or neutron reflection faces (21,22,23) formed at predetermined asymmetry angles to a Bragg diffraction plane in the respective crystal portion. The crystal portions are interconnected (25) to maintain a first and second (21,22) of these faces spaced apart for receipt of a sample (8) between them and to allow small adjustments of the relative angle of the faces about the normal to the plane of diffraction while maintaining the normals to the Bragg planes for the first and second faces (21,22) substantially in the plane of diffraction. First face (21) is arranged to be a monochromator and collimator with respect to x-rays or neutrons of appropriate wavelength incident reflected through the sample for receipt by the second face (22), which thereby serves as an analyzer face.
