The Scanning Electron Microscopy Lab houses a JEOL JSM-6610LV scanning electron microscope (SEM). The SEM is equipped with a LaB₆ cathode and is coupled to a Bruker Quantax 800 energy-dispersive X-Ray spectrometer, a cathodoluminescence detector, and an electron-backscatter diffraction detector. The SEM is typically used for structural and chemical analysis of rocks, minerals, and fossils. The large sample chamber holds objects up to ten centimeters in size. The SEM can be operated in a low-vacuum mode so that also uncoated (as-is) or not fully vacuum-resistant samples can be examined. Using an e-flash EDS detector, element distribution maps in thin slices of rock can be created and special phases can be found in a short time.
