Phenom Pharos G2 – Desktop Scanning Electron Microscopes

Tabletop field emission gun scanning electron microscope for high quality imaging across disciplines.

Field emission gun scanning electron microscope

The Thermo Scientific Phenom Pharos G2 FEG-SEM brings field emission SEM to your tabletop. The Phenom Pharos G2 FEG-SEM will outperform many floor-standing SEMs in terms of image quality, while offering a vastly better user experience. For academic and industrial laboratories that so far did not consider SEM a realistic option, the Phenom Pharos G2 FEG-SEM makes FEG performance accessible thanks to its attractive form factor and short training required. Blazing fast sample loading means fast sample exchange, which means higher productivity. Unlike other SEMs, which end up being fully booked, the Phenom Pharos G2 FEG-SEM performs imaging and analysis jobs so quickly that it serves well as a walk-up tool.

The new Phenom Pharos G2 FEG-SEM expands its acceleration voltage range down to 1 kV, to better accommodate insulating and beam-sensitive samples, and up to 20 kV, with a resolution of 2.0 nm that reveals the finest details.

Unique field emission source

Unique among desktop SEMs, the Phenom Pharos G2 FEG-SEM offers a field emission source, which guarantees high brightness, crisp images, and stable beam current.

Excellent resolving power

The Phenom Pharos G2 FEG-SEM offers a resolution of 2.0 nm at 20 kV. Such performance shows the shape of nanoparticles, imperfections in coatings, or other features that would be missed by tungsten SEMs or other tabletop SEMs.

Gentle imaging

With a voltage range down to 1 kV, the Phenom Pharos G2 FEG-SEM enables imaging of beam-sensitive samples, such as polymers, as well as insulating samples, without the requirement to apply a coating. As a result, nanoscale surface features are not obscured.

Higher productivity

While FEG SEMs have a reputation for being difficult to accommodate and difficult to operate, the Phenom Pharos G2 FEG-SEM literally requires only a desk, and less than one hour of training. Master students, visitors, or other researchers typically not trained to work on high-end FEG SEMs can easily use the Phenom Pharos G2 FEG-SEM to create eye-catching images.

A world of information

On the Phenom Pharos G2 FEG-SEM, morphological information is acquired together with compositional information, thanks to SE, BSE, and EDS detectors built into the system. A range of sample holders is available for temperature-controlled or electrical experiments.

Process control using electron microscopy

Modern industry demands high throughput with superior quality, a balance that is maintained through robust process control. SEM and TEM tools with dedicated automation software provide rapid, multi-scale information for process monitoring and improvement.

Quality control and failure analysis

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.

Fundamental Materials Research

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.

Energy Dispersive Spectroscopy

Energy dispersive spectroscopy (EDS) collects detailed elemental information along with electron microscopy images, providing critical compositional context for EM observations. With EDS, chemical composition can be determined from quick, holistic surface scans down to individual atoms.

EDS Elemental Analysis

Thermo Scientific Phenom Elemental Mapping Software provides fast and reliable information on the distribution of chemical elements within a sample.

3D EDS Tomography

Modern materials research is increasingly reliant on nanoscale analysis in three dimensions. 3D characterization, including compositional data for full chemical and structural context, is possible with 3D EM and energy dispersive X-ray spectroscopy.

Atomic-Scale Elemental Mapping with EDS

Atomic-resolution EDS provides unparalleled chemical context for materials analysis by differentiating the elemental identity of individual atoms. When combined with high-resolution TEM, it is possible to observe the precise organization of atoms in a sample.

Imaging Hot Samples

Studying materials in real-world conditions often involves working at high temperatures. The behavior of materials as they recrystallize, melt, deform, or react in the presence of heat can be studied in situ with scanning electron microscopy or DualBeam tools.

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.
