Arizona LaserChron Center 

Scanning Electron Microscope & Raman Lab

Gould-Simpson Room 130

The SEM/Raman lab is supported by the National Science Foundation (EAR 2050246) as part of the Arizona LaserChron Center.

Facility equipment:

The Arizona Laserchron Center (Department of Geosciences, University of Arizona) hosts a microanalysis lab equipped with an Hitachi S-3400N variable-pressure scanning electron microscope (SEM) and a Renishaw Raman Spectroscopic system. The S-3400N SEM utilizes a Tungsten filament electron source and provides an analytical spot-size of approximately 1um in diameter.

Additional detectors for the SEM include:
