Helios G4 Ux Dual Beam
Helios G4 UX Dual Beam (electron & ion beams) microscope is designed for the highest-quality imaging, ultra-thin TEM and APT sample preparation, milling and deposition of complex structures with critical dimensions of less than 10 nm, multi-modal subsurface and 3D data collection.
- Electron beam imaging provides the most complete sample information with sharp, refined, and charge-free contrast obtained from 5 integrated in-column and below-the-lens detectors.
- Reveal the finest details with the next-generation UC+ monochromator technology with higher current, enabling sub-nanometer performance at low energies
- The highest quality, multi-modal subsurface and 3D information with the most precise targeting of the region of interest using optional Auto Slice & View™ 4 (AS&V4) software.
- Precise sample navigation tailored to individual application needs thanks to the high stability and accuracy of the 150 mm Piezo stage and in-chamber Nav-Cam.
- Artifact-free imaging based on integrated sample cleanliness management and dedicated imaging modes such as SmartScan™ and DCFI (drift correction frame integration).
