Zeiss Ultra SEM
Ultra High Resolution Field Emission SEM
Manager: Alan R. BleierBackup: John Treichler , Amrita Banerjee
Scanning electron microscopy is critical for the analysis of nanoscale materials and structures. CNF operates two field emission scanning electron microscopes (SEMs): a Zeiss Supra 55 microscope capable of variable pressure (VP) operation and a Zeiss Ultra 55 microscope optimized for high resolution imaging. Like most modern SEMs, both systems are capable of operating at beam energies from 100 V to 30 kV. However, the unique electron optical design employed in the Zeiss systems enables unsurpassed performance at beam energies from 100 V to 8 kV. This is crucial for obtaining high resolution distortion free images of surface.
