Highly Annealed Pyrolytic Graphite (HAPG) was developed around 10 years ago by the Company Optigraph. Soon, first experiments demonstrated its potential for high resolution X-ray spectroscopy, namely X-ray Absorption Spectroscopy (XAS) and X-ray Emission Spectroscopy (XES). Meanwhile, spectrometer for XAS as well as for XES are in operation, which use X-ray tubes as sources and are suitable for the analysis of samples from chemical or materials research. The contribution will begin with a general discussion of design fundamentals for HAPG based high resolution spectrometer. This includes considerations regarding resolving power, spectrometer dimension, optic alignment, etc. Setups for XES and XAS which are in operation are presented. The fields of applications are discussed and examples are shown.
