Double-Corrected Monochromated Spectra 300 S/TEM

The ThermoFisher Spectra 300 S/TEM (60–300 keV) is a high-resolution aberration corrected scanning transmission electron microscope. The microscope is equipped with a high-brightness X-FEG source, Cs CETCOR image and S-CORR probe corrector system, Lorentz lens, Super-X EDS detector, DualEELS, and 4D STEM detectors. A suite of sample holders offers a wide range of in situ and operando TEM capabilities.

Microscope installation currently in progress..
