Phenom Pharos G2
The Thermo Scientific Phenom Pharos G2 is a desktop FEG-SEM (Field Emission Gun – Scanning Electron Microscope). It’s designed to make SEM more accessible, with advanced nanomaterials research capabilities.
The Phenom Pharos G2 tabletop microscope makes it easier to characterise the size, shape and chemical composition of a wide range of nanoparticles at high resolution.
The Phenom Pharos G2 progresses nanomaterial research by delivering high resolutions and a wide acceleration voltage range, all in a desktop system that can fit within a lab or office. From more advanced textiles and food packaging to improved solar and wind energy, this easy-to-use instrument supports rapid innovation for a wide range of industries.Rosy Lee, Vice President and General Manager of Materials Science at Thermo Fisher
The Phenom Pharos G2 is intuitive to use, high throughput and versatile for high-volume industrial and academic labs.
- High-resolution imaging at 2.0 nm, compared to 2.5 nm with the previous model.
- Wider energy range: 1-20 kV acceleration voltage range for a wider range of samples, including insulating and beam-sensitive materials.
- Fast time-to-image of just 30 seconds, for high throughput.
- Easy to use, with intuitive user interface and workflows.
- Quick installation: 40% faster than the previous version, to get you up and running sooner.
- Enhanced reliability: Robust parts and an integrated power supply for reproducible data and minimal interruptions to your work.
2.0 nm Resolution for Fine Details
In materials science, the Phenom Pharos G2 can resolve the morphology of nanomaterials in metals, minerals, ceramics and more with 2.0 nm resolution at 20 kV. This is useful in manufacturing, electronics, clean energy and many other fields.
Insulating and Beam-Sensitive Materials
For soft, beam-sensitive or insulating samples you can image at low energy levels down to 1 kV. This provides high-resolution insights into polymers and multi-layer organic films without damaging or obscuring their nanoscale features.
With low acceleration voltages, no coating or preparation is necessary to protect beam-sensitive samples. On the pharmaceutical powder below you can see the sample damage at 5kV, but at 1 kV it remains intact, highlighting the value of low-kV imaging for sensitive samples.
The example below is of a sea shell: an uncoated insulator that needs low acceleration voltage. At 2 kV there are significant charging artefacts. In comparison, in the bottom image at 1 kV, the artefacts disappear.
Easy to Use
FEG-SEMs typically have a reputation for being awkward to accommodate and difficult to use.
All the Phenom Pharos requires is a sturdy table and a regular power outlet. It doesn’t need a dedicated room or special infrastructure. The UPS (Uninterrupted Power Supply) is integrated, to protect the system from any power outages.
With less than an hour of training, master students, visitors and other researchers not trained on high-end FEG SEMs can easily acquire eye-catching images.
Sample loading is easy – simply insert the holder. An optical image appears instantly. This is used for initial navigation and then throughout the SEM session. When SEM mode is switched on, an image appears in 30 seconds.
The user interface displays a 24″ full-screen SEM image with an incredible amount of detail. The controls makes it easy to zoom in and navigate around the sample.
While SEMs typically end up being fully booked, the Phenom Pharos G2 is so fast that it can be used as a walk-up system.
