The Stanford EARTH Scanning Electron Microscope Facility is equipped with a new, state-of-the-art, JEOL JSM-IT500HR environmental scanning electron microscope. This high resolution microscope features a high-brightness field emission source and integrated backscattered electron (BSE) and secondary electron (SE) detectors. The system is also equipped with a Thermo Scientific energy-dispersive spectrometer (EDS) featuring the powerful Thermo Scientific Pathfinder Pinnacle analysis software. The EDS system allows for the rapid acquisition of high resolution X-ray maps and features a variety of spectroscopy tools making phase mapping and spatial-compositional analyses instantaneous. The IT500HR is also equipped with a Centaurus monochromatic cathodoluminescence (CL) detector.
