DualBeam Scanning Electron Microscope

FEI Helios Nanolab™ G3 DualBeam™ Focused Ion Beam-Scanning Electron Microscope


The FEI Helios Nanolab G3 DualBeam  FIB-SEM platform is designed to access a new world of extreme high resolution 2D and 3D characterization. Precise FIB slicing, combined with a high precision piezo stage and superb SEM performance support automated software for high-resolution sample surface montaging, unattended sample preparation, or 3D characterization. Serial slicing and imaging using the AutoSlice and View™ software creates a 3D-image stack with 4-nm isotropic resolution that may be reconstructed in separate software for high resolution visualization. Traditional SEM imaging allows high-resolution detail of sample surfaces of all types and materials to be quickly and easily elucidated.


  • Ideal for the analysis of surface topographies or post-fixed resin-embedded samples by secondary or backscatter electron detection using the ETD, retractable CBS, and in-column TLD, MD, or ICD detectors.
  • The focused gallium-ion beam ablates fine slices as thin as 4-nm to reveal structure under the resin block surface in order to provide a novel 3D picture of the sample volume.
  • Maps™ software package allows large-format montaging over hundreds of micrometers, providing a “Google Street View”-like dataset.
  • Imaging data from any outside source may be imported and correlated in the Maps software for Correlative Light and Electron Microscopy (CLEM)
  • A retractable STEM detector allows low-voltage (10-30 keV) screening of TEM specimens.

ZEISS Crossbeam 550 Microscope with Cryo-stage and Atlas 5 Software

About the Crossbeam

The ZEISS Crossbeam 550 SEM combines high resolution, contrast, and signal-to-noise ratios of the GEMINI II column with the precise milling of the next-generation Ion-sculptor focused ion beam column.  The Atlas 5 software can be used for automatic 3D image acquisition using FIB milling of bulk samples or array tomography of serial sections on coverslips.  The microscope is additionally equipped with a cryo-stage that allows for imaging and automated TEM lamella preparation of frozen, vitrified samples.


  • Isotropic 3D data acquisition
  • 6-axes motorized super-eucentric stage
  • Cryo capability using the Leica EM VCT500
  • Less than 2.0 nm SEM resolution at all keVs
  • 3 nm ion beam resolution
