Scanning Electron Microscopy
The picture is of Magnesium Oxide, at 60,000x magnification. The photo was taken using a Scanning Electron Microscope here on campus with a SEI detector. To achieve a high resolution, the sample was focused at 120,000 magnification, with a working distance of 3mm, then backed out to 60,000x.
