Two scanning electron microscopes are part of the FCEM. 

The FEI Helios is a dual beam machine (focused-ion beam in addition to the electron beam) that is heavily used mainly by cellular biology groups. The volume imaging capabilities of this system are in the process of being strengthened by implementing serial block face scanning EM (SBF-EM). 

Classical SEM imaging is done on an FESEM S-4500 I.
