This is the first desktop SEM solution from Thermo Fisher Scientific with resolutions below 
3 nm
 and a field emission gun (FEG) 
for crisp high-quality images with magnifications of up to one million times in just 30 seconds.

The Phenom Pharos is the only desktop scanning electron microscope (SEM) designed with the power of a FEG source, delivering high resolution images in the same intuitive and compact design that has made the Phenom the worlds best selling tabletop SEM. The optional secondary electron detector (SED), energy-dispersive X-ray detector (EDX), and sophisticated suite of analytical software allow a detailed analysis of any sample. The innovative design of the Phenoms provides a list of advantages over every other desktop SEM:

  • Only 30 seconds from sample loading to imaging. The Phenom Pharos desktop SEM is the fastest SEM.
  • Multiple acceleration voltages
  • Motorized XY stage
  • Color optical camera for single-click navigation
  • Elemental analysis with EDS option
  • Secondary electron detector option
  • Small footprint
  • No infrastructure needed
