Jeol JSM 6400 Scanning Electron Microscope

The Jeol JSM-6400 is a SEM configured with a Noran energy dispersive X-ray analyzer (EDS system). SEM is a method for high-resolution imaging of surfaces. An incident electron beam is scanned across the sample’s surface, and the resulting electrons emitted from the sample are attracted and collected by a detector and translated into a signal. Imaging in a SEM can be done using secondary electrons to obtain fine surface topographical features or with backscattered electrons which give contrast based on atomic number. The EDS analysis system enables the SEM to perform compositional analysis on specimens.
