My new dual-beam SEM - FEI Versa 3D
As some of you have probably already heard, some time ago I got myself a FEI Versa 3D - dual-beam Schottky field-emission SEM, with EDS/EBSD detectors and platinum deposition. This has been my dream for quite some time, and it is surreal that it is finally here. Schottky field-emission SEM is a good middle ground (between cold field-emission and tungsten filament) - quite robust and stable, yet…
