Working Principles

FETEM combines a 200kV field emission gun (FEG) and in in-column energy filter (Omega Filter) to produce a high-end, optimally configured TEM for energy filtered imagery and chemical analysis of specimens.

This also utilizes a rotation-free image-forming optical system which not only facilitates acquisition of TEM images and diffraction patterns but also produces stable spectra data.
