Advantages: 
Tracking
  • Live tracking or stage calibration methods for tracking specimen drift and stage movement
  • Manual override mode for extreme low contrast specimens or a particularly poor stage
  • Tracking data can be used to reduce dose on subsequent acquisitions or to improve tracking at high magnifications
  • Intelligent prompting when drift becomes excessive
Report generation
  • Graphical output of tracking data measured during series acquisition
  • Graphical output of stage calibration used, or stage calibration for current holder
  • Log of corrections applied as series acquisition proceeds
  • Summary of experiment setup from tilt series
2D Visualization
  • Step through acquired series and view individual planes
  • Play tilt series as a movie and export to movie format
Data access
  • During acquisition data can be saved plane-by-plane to file or stored in memory, or both
  • 3D series can be saved in *.DM3 or other formats for import into other reconstruction and visualization packages
  • Access data through the powerful DigitalMicrograph® scripting language
Compatibility
  • Compatible with a broad range of microscopes equipped with computer controlled stages; see the particular mode of interest for further details

TEM Tomography

The TEM Tomography software enables collection of data in TEM mode on any microscope equipped with the following computer controllable components: objective lens, image-shift deflectors, beam-shift deflectors, and a tilting stage. Drift corrections are performed by means of the objective lens and image-shift, beam-shift deflectors.

  • Supports any Gatan digital camera
  • Z-tracking through beam-tilt induced image-shift method   

STEM Tomography

The STEM Tomography software enables collection of data in STEM mode on a microscope equipped with the following computer controllable components: condenser lens and/or objective lens, and a tilting stage. The microscope must be equipped with a DigiScan scan generator (DigiScan I or DigScan II) and compatible STEM detector. 

  • Supports a wide range of DigiScan compatible STEM detectors
  • Novel Z tracking algorithm tested successfully on precipitates, nanowires, calibration gratings and more with accuracy to better than one nanometer
  • X and Y drift correction with sub pixel accuracy
  • Focus dynamically adjusted through acquisition of each image to ensure focus on tilted specimens
  • Independent magnification levels for tracking and data acquisition
  • Simultaneous STEM signal acquisition—e.g., bright field and high angle annular dark field signals  

EFTEM Tomography

The EFTEM Tomography software enables collection of data from a microscope equipped with an energy filter. The filter can be either a Gatan imaging filter or certain JEOL or ZEISS in-column filters equipped with a Gatan CCD camera. The microscope must be equipped with the following computer controllable components: objective lens, image-shift deflectors, beam-shift deflectors, and a tilting stage. 

  • The only commercial software which enables EFTEM tomography
  • Acquire an EFTEM tilt series on any TEM equipped energy filter (Gatan imaging filter or an in-column filter) and a Gatan camera
  • Track X,Y and Z drifts at any energy loss or with zero-loss or unfiltered images
  • Periodically adjust the filter to correct energy drift (available on Gatan imaging filters only)
  • Full support for jump-ratio, elemental or thickness mapping
