Helios 5 Laser PFIB System

FIB SEM laser tool for high throughput millimeter scale cross sectioning and 3D characterization with nanometer resolution

The Thermo Scientific Helios 5 Laser PFIB System combines the best-in-class monochromated Elstar Scanning Electron Microscopy (SEM) Column with a plasma focused ion beam (PFIB) and a femtosecond laser to produce a high-resolution imaging and analysis tool with in-situ ablation capability, offering unprecedented material removal rates for fast millimeter-scale characterization at nanometer resolution.

Key Features


Fast material removal

Millimeter-scale cross sections with up to 15,000x faster material removal than a typical gallium focused ion beam.

Accurate and repeatable cut placement

The same coincident point for all 3 beams (SEM/PFIB/laser) enables accurate and repeatable cut placement and 3D characterization.

High throughput processing of challenging materials

Includes non-conductive or ion-beam-sensitive samples.

Shares all capabilities of the Helios 5 PFIB platform

High-quality gallium-free TEM and APT sample preparation and high-resolution imaging capabilities.

Statistically relevant subsurface and 3D data analysis

Acquire data for much larger volumes within a shorter amount of time.

Fast characterization of deep subsurface features

Extraction of subsurface TEM lamella or chunks for 3D analysis.

Fast and easy characterization of air-sensitive samples

No need to transfer samples between different instruments for imaging and cross-sectioning.
