Application | S/TEM Spectroscopy
Stimulated EELS and EEGS
Detect near-field optical responses in supported S/TEM installations without detector or column modifications.
S/TEM
An onboard pulser is standard on this system, enabling pulse widths as short as 50 ns with compatible CW lasers.
Photon In
Continuous-wave laser stimulation
Electron Signal
Energy gain and loss examples
Detector
Existing S/TEM spectroscopy context
Platform
S/TEM only
Why It Matters
Reach Gain-Side Physics Without Rebuilding The Microscope.
In publication-backed examples, optical stimulation can populate near-field modes so electrons exchange energy with the stimulated sample response. This is a specialized S/TEM application, not a general SEM/FIB or tabletop SEM route.
What This Enables
Application Capabilities.
Optical excitation paired with S/TEM spectroscopy
Irradiance-dependent experiment planning
Comparison of electron spectra with and without optical stimulation
Aether coordination where installed hardware supports the experiment
Not currently available for SEM/FIB or Tabletop SEM
