3D Tomography Acquisition
For tomographic tilt series acquisition (TEM, STEM & EFTEM)
Electron tomography is a method for determining 3D structures. Gatan’s 3D Tomography Acquisition Software acquires a series of projections using your electron microscope, tilting the sample by a small increment between each projection. Gatan’s 3D Reconstruction Module can then be used to align the data and generate a 3D volume.
Tracking
- Live tracking and stage calibration methods to track specimen drift and stage movement
- Manual override mode for excessively low contrast samples and poor stages
- Tracking data can be used to reduce dose on future acquisitions and improve tracking at high magnification
- Intelligent prompting when there is too much drift
Reports
- Tracking data and stage calibration reports
- Log of corrections applied as the series acquisition progresses
- Summary of experiment set-up from tilt series
2D Visualisation
- Step through the series of images and examine individual planes
- Play the tilt series as a video, which can be exported
Compatibility
- Compatible with a wide range of microscopes with computer-controlled stages.

TEM Tomography
Collect data in TEM mode using any microscope.
Drift correction is performed using the objective lens and image-shift, beam-shift deflectors.
- Compatible with all Gatan digital cameras
- Z-tracking through beam-tilt induced image-shift method
Computer-controlled hardware required:
- Objective lens
- Image-shift deflectors
- Beam-shift deflectors
- Tilting stage
STEM Tomography
Collect data in STEM mode on your microscope.
- Use with a wide range of DigiScan compatible STEM detectors
- New Z-tracking algorithm for better than one nanometre accuracy, suitable for precipitates, nanowires, calibration gratings and more
- X and Y drift correction with sub-pixel accuracy
- Focus automatically adjusts throughout the acquisition series
- Independent magnification levels for tracking and data acquisition
- Simultaneous STEM signal acquisition eg bright and high angle annular dark field signals
- Condenser and/or objective lens
- Tilting stage
- DigiScan scan generator
- Compatible STEM detector
EFTEM Tomography
Collect data from your TEM equipped with an energy filter. This is the only commercial software available for EFTEM tomography.
- 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 (Gatan imaging filters only)
- Perform jump-ratio, elemental and thickness mapping
- Gatan imaging filter or certain other in-column filters together with a Gatan CCD camera
- Objective lens
- Image-shift deflectors
- Beam-shift deflectors
- Tilting stage
