Description
We have two advanced Scanning Electron Microscopes (SEM) the ZEISS MERLIN FEG-SEM with Oxford EBSD & EDS and the Thermofisher APREO SEM.
The Merlin has excellent beam control down to low accelerating voltages and high currents to allow some of the highest resolution characterisations of bulk materials currently possible. Incorporating both a sample exchange airlock and an integrated plasma cleaner to ensure chamber cleanliness.
Alongside the Oxford Instruments EBSD detector for crystallographic information, the Merlin is equipped with two large area EDS detectors to maximise signal collection, even at extreme beam conditions for chemical distribution mapping. In addition, a windowless EDS detector is installed that ensures characterisation capability is not lost when working at low accelerating voltages.
