ABSTRACT:
An x-ray or neutron optic configuration includes a plurality of single crystal portions formed with respective spaced x-ray or neutron reflection faces formed at predetermined asymmetry angles to a Bragg diffraction plane in the respective crystal portion. The crystal portions are interconnected to maintain a first and second of these faces spaced apart for receipt of a sample 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 substantially in the plane of diffraction. A first face 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, which thereby serves as analyzer face.
