In this video tutorial (as always, recorded raw, unedited, unfiltered, and uncensored), I cover how to properly focus in both TEM and STEM modes as demonstrated using a FEI Talos F200i S/TEM. The topics covered include:
1. setting and verifying eucentric height
2. microprobe and nanoprobe modes for TEM and STEM operation
3. objective lens settings for microprobe and nanoprobe modes
4. properly setting the C2 lens for STEM mode
5. coarse focusing by adjusting stage Z
6. fine focusing by adjusting the objective lens
7. deviations from eucentric height in STEM mode
8. monitoring the deviation (defocus) from eucentric focus
Thanks for watching! Please like, subscribe, and share and let me know if you have any questions or comments. Video topic requests are always welcome and appreciated; I enjoy making these videos and wish I could make them more frequently, but the demands of my job make it tough to do so; I’m in charge of 3 S/TEMs, 2 dual FIB/SEM systems, and 1 SEM and this keeps me very busy!
