Scanning electron microscopes (SEMs) generate images by scanning a sample with a focused beam of electrons. The interaction of the electrons with the sample material produces signals that contain information about surface topography and composition. With instruments capable of sub-nanometer resolution, high contrast, and compatibility with a wide variety of samples, the range of analysis that SEM can support has never been broader.
Thermo Fisher Scientific is dedicated to producing analytical SEMs that are ideally suited for your specific needs. We offer a range of versatile tools, everything from our easy-to-use Thermo Scientific Phenom Desktop SEMs to powerhouse instruments capable of unparalleled resolution and contrast like the Thermo Scientific Verios SEM.

The Thermo Scientific Phenom product line redefines speed, ease-of-use and performance thanks to its innovative, user-friendly design and software, which allows even novice users to obtain an SEM image in minutes. Not only that, but the cutting-edge Phenom Pharos SEM even features a field emission gun (FEG) source, enabling resolutions below 3 nm.
Entry-level and environmental floor-model SEMs
Our versatile Thermo Scientific Prisma E and Thermo Scientific Quattro SEMs are the ideal choice if sample flexibility is a priority. These instruments are capable of remarkable all-around performance under a range of conditions due to their low vacuum modes, enabling the analysis of charging, outgassing or otherwise difficult samples. High stability and ease of use (as well as a selection of optional accessories and a highly modular analytical chamber) make these instruments the tools of choice for multi-user labs.
Both instruments feature the optional Thermo Scientific ColorSEM Technology, which colorizes the greyscale SEM image in real time according to elemental composition using combined SEM and EDS imaging.
If you would like to maximize resolution and contrast, look no further than our revolutionary Verios and Apreo SEMs. These instruments are committed to obtaining the most detailed information possible, with the excellent contrast and resolution of the Apreo SEM only matched by the world-leading performance of the Verios SEM.
