STEMPack Spectrum Imaging

For electron microscopes with scanning mode

Acquire detailed analytic data from your sample using an electron microscope with scanning mode, with the Gatan STEMPack system. Multi-modal data in scanning mode gives you a wealth of information from precise positions within a scanned image or line profile. This is the basis for a range of techniques known as spectrum imaging (SI).


Detailed analytical data

Acquire a wealth of information.

Rich spectral information

With high spatial resolution.

Simple but flexible software

To help you achieve excellent results.

Virtually any signal can be a spectrum image

Acquire almost any signal produced in the electron microscope.


Spectrum imaging acquires the maximum possible information from a specific area of the sample. The procedure is fully automated. STEMPack is compatible with a range of detectors including:

  • EELS (Electron Energy Loss)
  • Characteristic x-ray emission (EDS)
  • Cathodoluminescence emission (CL)
  • Aabsorbed / induced current (EBAC/EBIC)
  • Electron diffraction

The spectral data is analysed with powerful processing and visualisation processes to uncover unique details. The detail of the spectral information, together with the high spatial resolution makes this an extremely powerful electron microscopy technique

  • Acquisition options to give you flexible data without artefacts.
  • Simple analysis of dense data sets with a single application; directly cross reference data and results
  • Choose your data size and region 
  • Acquire virtually any signal produced in the electron microscope as part of a spectrum image
  • Richly detailed mapping
