The FEI Talos F200i S/TEM is a state-of-the-art field emission gun scanning/transmission electron microscope capable of providing micro- to atomic-scale structural, morphological, and chemical information.

Instrument Specifications:

  • Configured for 80 or 200 kV operation
  • X-twin objective lens (Cs = 1.2 mm at 200 kV) with single-, and double-tilt (hex ring) holders available
  • Bottom-mounted FEI Ceta 16 megapixel CMOS camera; Fischione Instruments Model 3000 HAADF-STEM detector; FEI BF/DF STEM detectors; DPC imaging capable
  • 0.34 nm point-to-point resolution in conventional TEM imaging (at 200 kV); 0.24 nm Scherzer resolution in HR-TEM imaging (at 200 kV); 136 pm STEM resolution (at 200 kV)
  • Bruker XFlash 6T|30 windowless silicon drift detector (30 square mm detector area) energy dispersive spectroscopy system

  • YouTube video playlist (tutorials, concepts, and fundamentals related to TEM)
