OPTICAL DEVICE FOR ANALYZING A SPECIMEN BY THE SCATTERING OF AN X-RAY BEAM AND ASSOCIATED COLLIMATION DEVICE AND COLLIMATOR.

摘要

A collimation device for an X-ray beam, an optical device for analyzing a specimen by the scattering of an X-ray beam, and a collimator for an X-ray beam. The collimation device includes an enclosure configured to be under a vacuum or a controlled atmosphere, the enclosure including an inlet and an outlet for the X-ray beam and at least one plate made of a material having a diffracting periodic structure, the plate including two main faces and at least one flared aperture between the faces.
