The LEO Ultra 55 is a dedicated high vacuum and high resolution SEM that allows for imaging with a resolution down to 1 nm. The instrument has a field emission gun and is also equipped with an EDX (energy dispersive X-ray) detector for chemical analysis, an EBSD (electron backscattered diffraction) detector for grain orientation and texture analysis, and a STEM (scanning transmission electron microscopy) detector for thin foil analysis.
