Thermo Scientific Helios 5 PFIB Laser Systems combine plasma focused ion beam milling with femtosecond laser ablation and SEM (scanning electron microscopy) imaging. This “TriBeam” combination enables high-resolution imaging and analysis with in situ ablation capability, offering unprecedented material removal rates for fast millimeter-scale characterization at nanometer resolution.
The femtosecond laser can cut many materials at rates that are orders of magnitude faster than a typical FIB. A large cross-section (hundreds of micrometers) can be created in less than five minutes. Because the laser has a different removal mechanism (ablation versus the ion sputtering of FIB), it can easily process challenging materials, such as non-conductive or ion-beam-sensitive samples.
The extremely short duration of the femtosecond laser pulses introduces almost no artifacts such as heat impact, microcracking, melting, or those typical of traditional mechanical polishing. In most cases, the laser-milled surfaces are clean enough for direct SEM imaging and even for surface-sensitive techniques such as electron backscatter diffraction (EBSD) mapping.
We offer a broad product portfolio and advanced automation capabilities for applications such as transmission electron microscopy (TEM) sample preparation, atom probe tomography (APT) sample preparation, and 3D structural analysis.
Built on the proven Helios 5 DualBeam platform, these instruments incorporate a suite of state-of-the-art technologies to provide high-performance, high-resolution transmission electron microscopy (TEM) and atom probe tomography (APT) sample preparation and extremely high-resolution SEM imaging with precise materials contrast.
When combined with Thermo Scientific Auto Slice & View Software, TriBeam instruments provide 3D insight into sample structure by selectively removing (milling) the material for subsurface characterization. Digital reconstruction generates multi-modal 3D datasets that can consist of a variety of signals, including backscattered electron (BSE) imaging for maximum materials contrast, energy dispersive spectroscopy (EDS) for compositional information, and electron backscatter diffraction (EBSD) for microstructural and crystallographic information. The SEM capability of TriBeam instruments offers nanoscale details across a wide range of working conditions, from structural information obtained at 30 keV in STEM mode to charge-free, detailed surface information at lower energies. With unique in-lens detectors, TriBeam systems are designed for simultaneous acquisition of angular/energy-selective secondary-electron and BSE data. Fast, accurate, and reproducible results are provided by our unique SEM column design, which features fully automated lens alignments.
Thermo Fisher Scientific offers a broad range of (P)FIB-SEM systems with fully integrated femtosecond lasers. This TriBeam product family consists of three models, all featuring the best-in-class Thermo Scientific Elstar SEM Column, a high-precision 150 mm piezo stage, and a large chamber. The main difference between these models is the FIB column:
Millimeter-scale cross sections with up to 15,000x faster material removal than a typical focused ion beam.
Data acquisition for much larger volumes within a shorter amount of time.
Same coincident point for all tree beams (SEM / (P)FIB / laser) enables accurate and repeatable cut placement and 3D characterization.
Extraction of subsurface TEM lamella or chunks for 3D analysis.
Includes non-conductive or ion-beam-sensitive samples.
No need to transfer samples between different instruments for cross-sectioning and imaging.
High-quality TEM and APT sample preparation and high-resolution imaging capabilities.

Quality control and assurance are essential in modern industry. We offer a range of EM and spectroscopy tools for multi-scale and multi-modal analysis of defects, allowing you to make reliable and informed decisions for process control and improvement.
Novel materials are investigated at increasingly smaller scales for maximum control of their physical and chemical properties. Electron microscopy provides researchers with key insight into a wide variety of material characteristics at the micro- to nano-scale.
3D Materials Characterization
Development of materials often requires multi-scale 3D characterization. DualBeam instruments enable serial sectioning of large volumes and subsequent SEM imaging at nanometer scale, which can be processed into high-quality 3D reconstructions of the sample.
(S)TEM Sample Preparation
DualBeam microscopes enable the preparation of high-quality, ultra-thin samples for (S)TEM analysis. Thanks to advanced automation, users with any experience level can obtain expert-level results for a wide range of materials.
APT Sample Preparation
Atom probe tomography (APT) provides atomic-resolution 3D compositional analysis of materials. Focused ion beam (FIB) microscopy is an essential technique for high-quality, orientation, and site-specific sample preparation for APT characterization.
Cross-sectioning
Cross sectioning provides extra insight by revealing sub-surface information. DualBeam instruments feature superior focused ion beam columns for high-quality cross sectioning. With automation, unattended high-throughput processing of samples is possible.
In Situ experimentation
Direct, real-time observation of microstructural changes with electron microscopy is necessary to understand the underlying principles of dynamic processes such as recrystallization, grain growth, and phase transformation during heating, cooling, and wetting.
Multi-scale analysis
Novel materials must be analyzed at ever higher resolution while retaining the larger context of the sample. Multi-scale analysis allows for the correlation of various imaging tools and modalities such as X-ray microCT, DualBeam, Laser PFIB, SEM and TEM.
