Scanning Electron Microscopes

The Unit has three scanning electron microscopes available for staff and student use: The FEI NovaNano SEM, the Tescan MIRA3 RISE SEM and the Leo 1450 SEM. The instruments can be booked in advance for as long as is required for a particular experiment subject to user demand at that particular time. The Unit offers training in the operation of these instruments.
