Talos TEM

Description

The FEI Talos™ f200i S/TEM is a 200 kV field emission (scanning) transmission electron microscope that has been designed for fast, precise and quantitative characterization of nanomaterials; achieving atomic resolution. With column alignments at 120 kV and 200 kV the Talos™ f200i S/TEM is capable of imaging a broad range of materials science and biological samples.

The S/TEM column is fully automated, equipped with a S-FEG, isolated vacuum system for the electron gun, symmetric X-TWIN objective lens, computerized 5 axes eucentric goniometer, diffraction lens, intermediate lens, two projector lenses, fast survey camera, and a vibration-free vacuum system.

Techniques include: brightfield (BF), darkfield (DF), high resolution-TEM (HR-TEM for crystalline samples), diffraction, selected area electron diffraction (SAED), nanobeam diffraction, convergent beam electron diffraction (CBED), scanning transmission electron microscopy (STEM), high resolution-STEM (HR-STEM), and Energy Dispersive X-Ray Spectroscopy (EDS).
