Bruker D8 Advance with Goebel Mirror X-ray Diffractometer (XRD)

The Gobel Mirrors are synthetic crystals whose properties are defined by complex multi-layers which are deposited on silicon or glass substrates under ultra-high vacuum conditions. To shape the mirror, one of two methods is used. The most common is to carefully bend a silicon substrate, either before or after the multilayer structure is deposited, depending upon the application. For highly-demanding thin film requirements, the mirror can be fabricated using a preshaped quartz substrate.
