Welcome to the Electron Microscopy Facility at Trinity College

++++ Recipient of National Science Foundation Award for New SEM! ++++

The electron microscope (EM) is an important research-grade instrument that is used to study materials at the micro- and nano-structural level. EMs are used in medicine, industry, and academic settings around the world.

In 1996, Trinity College was awarded an NSF matching grant to build the nucleus for an interdisciplinary Electron Microscopy Facility to serve all the sciences. Today, that proposal has matured into the present-day EM Facility at Trinity College, with two transmission electron microscopes (one for life sciences and one for materials sciences), a scanning electron microscope, analytical support instrumentation, fully-featured sample preparation facilities, and both print and digital data acquisition capabilities. The resolution potential of the EMs at Trinity is measured in fractions of a nanometer!
Trinity also created a new full-time position in EM facilities management, to build courses, develop methodologies, operate and maintain the laboratories, and enable student and faculty researchers to make full use of the Facility. That position is currently held by Ann Lehman, who serves as Director of the Facility. An Electron Microscopy Advisory Committee (EMAC) provides oversight.
