ABSTRACT:
The invention relates to an X-ray diffractometer device, comprising an X-ray source, a collimator device for the source, a sample support, a collimator device for the beam reflected by the sample and a counter producing an output signal in the form of a voltage which is proportional to the number of photons reflected by the sample. This device furthermore includes a motor drive for the sample support, recording means for the signal Y originating from the proportional counter as a function of the angle .theta. between the plane of incidence of the sample and the incident beam, denoted X, mechanical means having a support for a plurality of filters having different coefficients of absorption and including a motor drive for this filter support, data processing means for selecting one of the filters of the filter support and for controlling the motor drive of the sample support, the motor drive of the filter support and the recording means, respectively.
