Scanning electron microscopes
Since the introduction of electron microscopes in the 1930s, scanning electron microscopy (SEM) has developed into a critical tool within numerous different research fields, spanning everything from materials science, to forensics, to industrial manufacturing, and even to the life sciences.
As soon as microscopic information about the surface or near-surface region of a specimen is needed, SEM becomes a necessary tool. For that reason, the method finds applications in nearly every branch of science, technology and industry.
Floor model SEMs offer the flexibility and versatility to meet a wide range of academic and industrial needs: support for large and heavy samples, a very wide range of accessories, excellent imaging quality for the most challenging materials or the smallest details, and dynamic experimentation.
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.

High-resolutions scanning electron microscopes
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.
Entry-level and environmental floor-model scanning electron microscopes
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.
Desktop scanning electron microscopes
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.
