Field Emission Scanning Electron Microscopy (FESEM) provides
topographical and structural information in plan or cross sectional
view. Used in conjunction with SEM, Energy Dispersive X-Ray
Spectroscopy (EDS or EDX) detects the elements present in a selected
area of the SEM image providing qualitative and quantitative
information. SEM applications include surface structure analysis, an
increased depth of field, backscatter imaging and morphology. EDS
applications include qualitative X-ray mapping, line scans and spot
analysis.
