The Panalytical XPert  x-ray diffractomer is a high resolution diffraction system consisting of a highly monochromatic beam with a well-defined wavelength and equatorial divergence. An X-ray mirror and a high-resolution monochromator are placed in line to deliver an incident X-ray beam that is not only highly monochromatic with a low divergence, but also has a high intensity. Reflectometry measurements can also be performed to identify layer thickness, density and surface roughness.
