ThermoScientific Helios G5 CXe Plasma FIB/SEM
The Helios 5 is a DualBeam focused ion beam microscope (FIB). It has an electron column for ultra-high-resolution scanning electron microscopy (SEM) tasks and a xenon (Xe) plasma ion column for sample preparation for TEM and atom probe tomography (APT), as well as for 3D characterization of materials.
Use of the Auto Slice & View software in combination with our Oxford Instruments Ultim®Max energy dispersive X-ray spectrometer (EDS) and/or Oxford Instruments Symmetry® Electron Backscatter Diffraction (EBSD) detector allows fully-automated multi-modal materials characterization workflows.
- Available detectors:
- in-lens SE/BSE detector (TLD)
- Everhart-Thornley SE detector (ETD)
- in-chamber electron & ion detector (ICE) for secondary ions (SI) and electrons (SE)

FEI Quanta 3D FEG FIB/SEM
The Quanta™ 3D DualBeam™ FEG FIB-SEM combines a Focused Ion Beam (FIB) with a high-resolution Field Emission Gun Scanning Electron Microscope (FEG-SEM). This combination provides enhanced 2D and 3D materials characterization and analysis for a wide range of samples.
A focused Ga Ion beam allows for micro and nano-scale cutting of material during TEM sample preparation, EBSD surface milling, and automated milling scripts for micro-pillar patterns. Additionally, the FIB provides a “slice and view” technique that allows for 3D reconstruction of a sample, providing the ability to image and analyze subsurface features. Featuring three imaging modes – high vacuum, low vacuum and ESEM, it accommodates the widest range of samples of any SEM system.
The Quanta 3D FEG’s novel, field-emission electron source delivers clear and sharp electron imaging and increased electron beam current enhances EDS and EBSD analysis.
The integrated EDAX Pegasus EDS & EBSD system brings new capabilities and flexibility to engineers and researchers needing chemical composition analysis, element distribution, crystallographic orientation, grain size and distribution etc.
