For materials science, Thermo Scientific Helios 5 Plasma FIB (PFIB) DualBeam focused ion beam scanning electron microscope, or FIB-SEM, offers unparalleled capabilities for gallium-free sample preparation, large-volume 3D characterization and high precision micromachining.
Key Features
Gallium-Free S/TEM and APT Sample Preparation
Gallium-free, high-quality TEM and APT sample preparation is made possible by the new PFIB column, which offers exceptional performance under all operating conditions and permits 500 V Xe+ final polishing.
Next-Generation 2.5 μA Xenon Plasma FIB Column
Using the newest generation 2.5 μA Xenon Plasma FIB column (PFIB), high throughput and quality statistically relevant 3D characterization, cross-sectioning, and micromachining are achieved.
Sub-Nanometer Performance at Low Energies
The best-in-class Elstar Electron Column and high-current UC+ monochromator technology, which enable sub-nanometer performance at low energies, reveal the smallest details.
Advanced Capabilities
Cutting-edge capabilities for ion and electron beam-induced deposition and etching on FIB/SEM systems using optional Thermo Scientific MultiChem or GIS Gas Delivery Systems.
Short Time to Nanoscale Information
Fastest access to nanoscale data for users of FLASH and SmartAlign technologies, regardless of skill level.
Advanced Automation
Automated multisite in situ and ex-situ TEM sample preparation and cross-sectioning with optional AutoTEM 5 software is the quickest and easiest method.
Multi-Modal Subsurface and 3D Information
Access high-quality, multi-modal subsurface and 3D information with precise targeting of the region of interest with the optional Auto Slice & View 5 (AS&V5) Software.
Complete Sample Information
The most comprehensive sample data was acquired from up to six integrated in-column and below-the-lens detectors with refined, sharp, and charge-free contrast.
Artifact-Free Imaging
Artifact-free imaging based on integrated sample cleanliness management and specialized imaging modes like DCFI and SmartScanTM Modes.
Precise Sample Navigation
The 150 mm Piezo stage's exceptional stability and accuracy, along with the optional in-chamber Nav-Cam, provide precise sample navigation that is customized to meet the needs of each specific application.
