DualBeam Microscope

Helios G4 UC for Materials Science

Enabling breakthrough innovations with DualBeam™ technology—faster and easier than ever before.

Scientists and engineers constantly face new challenges that require highly localized characterization of increasingly complex samples with ever smaller features. The latest technological innovations of the Helios G4 UC, in combination with the easiest to use, most comprehensive software and Thermo Fisher Scientific’s application expertise, allow for the fastest and easiest preparation of HR-S/TEM samples for a wide range of materials.

In combination with optional Auto Slice & View™ 4 (AS&V4) software, Helios G4 UC allows for the highest-quality, fully automated acquisition of multi-modal 3D datasets. These datasets include, among others, BSE imaging for maximum materials contrast, energy dispersive spectroscopy (EDS) for compositional information, and electron backscatter diffraction (EBSD) for microstructural and crystallographic information. Together with Avizo visualization software, this delivers a unique workflow solution for the highest-resolution, advanced 3D characterization and analysis at the nanometer scale.
