NEW PRODUCT LAUNCHING


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.

Key Features:

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.

 

Uncoated insulators, such as this sea shell, can only be properly imaged at low acceleration voltage. At 2 kV (left image), significant charging artefacts can still be observed. At 1 kV (right image), those artifacts have disappeared.


Sensitive materials require gentle conditions. With an acceleration voltage down to 1 kV, the Phenom Pharos G2 Desktop FEG-SEM images beam-sensitive samples without sample coating or other sample preparation. Left: pharmaceutical powder, imaged without damage at 1 kV. Right: the same sample imaged at 5 kV, with damage, illustrating the need for low-kV imaging.
