Imagine a Thermo Scientific Spectra™ 300 S/TEM:

  • That can truly be operated at different voltages (all the voltages between 30 and 300 kV for which alignments were purchased) in a single microscopy session
  • Where changing from an accelerating voltage to any other one takes about 5 minutes
  • That can accommodate a radically different EDX concept with a 4.45 srad solid angle (4.04 srad solid angle with an analytical double tilt holder)

With the new Spectra Ultra S/TEM, the accelerating voltage becomes an adjustable parameter, just like probe current, and the massive Ultra-X EDX system enables chemical characterization of materials too beam-sensitive for conventional EDX analysis.
