COVID-19: Essential Information

Scanning Electron Microscope (SEM)


The SEM is used to acquire high-resolution digital images and to analyze mineral compositions. It is equipped with secondary electron, backscatter, and cathodoluminescence. It is also equipped with an energy dispersive X-ray spectroscopy detector and an electron backscatter diffraction detector.

Students and faculty in the department use it to analyze metamorphic, igneous and sedimentary rocks as well as unconsolidated sediments from Lake Champlain. Students and faculty from the Biology Department and from the University of Vermont also use the facility.

Purchased in 2013 with funds from the George I. Alden Trust. Tescan Vega 3 LMU SEM with Oxford Instruments EDS & EBSD attachments.
