Zeiss SESAM

The Sub-Electron-volt Sub-Angstrom Microscope is a unique TEM, with a monochromator and an in-column MANDOLINE energy filter. The microscope column is suspended from an ultrastable support frame to provide excellent isolation. The SESAM was developed to provide the best performance in analytical electron microscopy combined with very high spatial resolution. It remains one of the best uncorrected TEMs for analytical work.
