Thermo Scientific Quasor™ EBSD: Microstructural Characterization in the SEM

The most productive EBSD technology available for examination of the microstructure of metals; the Thermo Scientific™ Quasor™ Electron Backscatter Diffraction (EBSD) system offers a highly efficient CMOS sensor designed to provide highly efficient characterization in the SEM.

This instrument is designed with the primary goal of increasing productivity; offering fast rates of collection and accurate indexing of electron backscatter diffraction patterns. The Quasor™ EBSD can operate under low light conditions and comes integrated with the Thermo Scientific™ Pathfinder™ X-ray microanalysis software. This acclaimed software is capable of simultaneously analyzing the microstructure of a material as well as its elemental chemistry, so that meaningful results can be acquired quickly and easily.

Quasor’s revolutionary CMOS camera offers metallurgists the ideal tool to improve throughput rates in their SEM lab, while gaining a more in-depth understanding of the materials they are studying.
