Nanoscience Instruments is proud to partner with Phenom World, leading global supplier of desktop scanning electron microscopes (SEM). Together, we continuously invest, develop and integrate our products to help customers improve their return on investment, time to data, and to increase system functionality.
The Phenom SEM is the most powerful tabletop SEM, providing a streamlined workflow to yield superior results. Key features contribute to these benefits, including:
The Phenom SEMs feature a CeB6 high brightness, long-life electron source that is superior to tungsten SEMs. A solid-state crystal electron source gives several benefits, including:
- 10x more electrons than tungsten
- Cleaner and tighter beam for higher resolution than tungsten filament SEMs
- Superior imaging at all kV ranges, especially low kV
- No need to auto-tune or recalibrate
- No catastrophic source failure during operation
The Phenom SEMs are equipped with an integrated backscattered electron detector (BSD). The four-quadrant solid-state backscatter electron detector used in Phenom SEMs:
- Detects elastically scattered electrons
- Provides material contrast
- Provides topographic imaging
- Allows for lower vacuum level to minimize beam damage and sample charging
- Results in orientation independent shading
Secondary electron detector (SED) images require complicated threshold image analysis because images are convoluted by shadows associated with the SED position. The inherent composition information and placement of the BSD combined with the high brightness electron source creates images with orientation independent shading with material contrast to allow for straightforward threshold analysis. This results in quantitative image processing that may also be automated to maximize workflow.

Crisp, high quality images are quickly acquired with the Phenom scanning electron microscope thanks to the electron source and BSD. Conductive and insulating samples can be imaged by the Phenom SEM without compromising the source lifetime thanks to the innovative column design.

The Phenom desktop scanning electron microscope is the ultimate all-in-one imaging and x-ray analysis system. Sample structures can be physically examined and their elemental composition determined. Viewing three-dimensional images of microscopic structures only solves half the problem when analyzing samples. It is often necessary to collect more than imaging data to be able to identify the different elements in a specimen. Using EDS with SEM addresses this need for elemental analysis.
Example of EDS spectrum for Phenom SEM
The EDS detector for the Phenom SEM:
- Is fully integrated
- Has a high input count rate
- Is easy to operate
- Does not require liquid nitrogen
The EDS software package runs smart algorithms with advanced peak analysis to optimize the auto-identification functionality, while still allowing for manual adjustments at any time in the analysis process. The intuitive step-by-step process within the software helps the user to collect all x-ray results in an organized and structured way.
The x-ray detector and control software are combined in one package. This Elemental Identification (EID) software package allows the user to program multiple point analysis and identify any hidden elements within the sample. Additionally, this software can be expanded with elemental mapping functionality. The step-by-step guided process within the EID software helps the user to collect all x-ray results in an organized and structured way.
Over 75% of SEM applications use magnifications between 1000x and 10,000x. The entry-level Phenom Pure is ideal for this imaging range. The Phenom Pure has an option to increase magnification to 65,000x.
The classic Phenom SEM systems are upgradeable. A Phenom Pure is easily upgradeable to a Phenom Pro, providing 130,000x magnification, higher resolution and more accelerating voltage. When elemental identification is needed, the Phenom Pro can be upgraded to a Phenom ProX, the ultimate tabletop SEM for imaging with EDS.
For large or multiple samples, the Phenom XL utilizes a large stage. The Phenom XL SEM includes an integrated BSD. EDS for elemental analysis and an integrated SED for topographic imaging are available.
The Phenom scanning electron microscope was designed to make SEM technology more accessible:
- Easy to use
- Minimal maintenance
- Intuitive software
- Never-Lost navigation correlating optical and electron image
- Small footprint with no infrastructure required
Additional software options can also be applied for maximum workflow. These include automated analysis of fibers, pores, or particles, surface roughness, and elemental analysis with EDS. Customized analysis is available using a scripting interface.
With images acquired in less than a minute after loading a sample, the Phenom SEM is a high throughput instrument. The Phenom SEM requires minimal maintenance and has a low cost of ownership.
- Long up-time
- Electron source does not require frequent tuning
- Dedicated operator is not needed
- Unique load-lock and vacuum reservoir
- Highly efficient pump down times
- Column protected from loose particles
- Vibration insensitive
- No additional infrastructure is needed
The Phenom SEM is an affordable SEM that has several advantages over outsourcing for SEM data and elemental analysis.
