Graphite optics consists of thin layers of Pyrolytic Graphite deposited on a substrate of focusing shape. Pyrolytic Graphite is a perfect artificial carbon obtained by annealing of carbon deposit at temperatures about 3000oC under deformation. Varying annealing procedure one could get Pyrolytic Graphite of different mosaic structure and mechanical properties. Graphite Optics made by Optigraph...

With the advent of synchrotron radiation facilities, scientists became familiar with high end X-ray analytical methods, e.g. X-ray emissions spectroscopy (XES) and X-ray absorption spectroscopy (XAS). Many of these experiments are equipped with crystal monochromators based on diffraction to ensure highest resolving power. To exploit new users and scientific fields for these methods,...

While Highly Oriented Pyrolytic Graphite (HOPG), a mosaic crystal of high integral reflectivity, has been successfully used in different XRF concepts as an effective X-ray focusing monochromator its further development enables new XAFS and XES configurations: Highly annealed pyrolytic graphite (HAPG) is an advanced type of pyrolytic graphite that, as a mosaic crystal, combines high integral...
