TFS Spectra 300 Kraken S/TEM + X-CFEG

TFS Spectra 300 Kraken S/TEM + X-CFEG:


  • Ultrabright cold field emission gun (CFEG) provides 10-fold improvement in brightness over the Titan STEM
  • Cs probe aberration corrector (S-CORR)
  • High-solid angle (1.7 Sr) x-ray detectors for sub-angstrom elemental mapping
  • Rapid EELS mapping at 0.3eV energy resolution with GIF Continuum + Dual EELS
  • EMPAD for electromagnetic field, strain and polarization mapping
