Field Emission Scanning Electron Microscope with EDS/EBSD-analysis

FE-SEM/EDS/EBSD

The laboratory consists of a variable pressure Tescan Mira3 High Resolution Schottky FE-SEM equipped with Oxford EDS and EBSD system and a CL system.

The instrument allows for:
•High-resolution imaging in both high- and low-vacuum mode
•Qualitative and quantitative elemental analyses
•Qualitative and quantitative line scans and elemental mapping
•Electron backscatter diffraction (EBSD) studies
•Cathodoluminescence imaging
