Scanning Electron Microscope

Cal Poly Humboldt houses a Quanta FEI 250 Scanning Electron Microscope that allows visualization of samples at anywhere from 20x to 10,000x magnification under high vacuum. Preparation of a sample for SEM viewing takes several days, culminating with removal of water content from the sample and a final coating of the sample's surface with a standardized layer of conductive material.
