Abstract:
A device for the precision rotation of samples on a diffractometer, comprising:a centering element which is held at one end of a motor-driven rotating shaft and can be displaced in a plane orthogonal to the axis of rotation of the rotating shaft, a sample holder2 which is fixed to the centering element or integral with the latter and which moves with the centering element when the centering element is displaced in the plane orthogonal to the axis of rotation of the rotating shaft, for holding a sample substantially centrally with respect to the axis of rotation in an X-ray or synchrotron radiation beam, at least one micrometer finger arranged in the region of the centering element in order to displace the centering element in a plane orthogonal to the axis of rotation of the rotating shaft, wherein the micrometer finger can be positioned orthogonally with respect to the axis of rotation of the rotating shaft by means of a micrometer finger drive device.
