Electron Microscopy

The goal of this site is to explain the basics of most electron microscopy methods without giving too much of the complex theory and mathematics behind it. Thus, reading these pages can in no way substitute the study of textbooks.

Does Your SEM Really Tell the Truth? - How would you know? Part 1

Understanding how image aquisition and instrument calibration is essential when making measurements using a high resolution scanning electron microscope. As the resolution of scanning electron microscope has increased it is essential to understand the factors that can contribute to potenial measurement errors. This well written article is highly recomended for those using SEM imaging for quantification of specimen features. Part 1 is avaialble for free download fron the NIST. Part 2 covering specimen contamination and methods of contamination elimination and part 3 covering contamination are only available for purchase.

Optimizing the Performance of a Tungsten Hairpin

To get the most out of a scanning electron microscope operators need to optimize the accelerating voltage, rightness of the electron gun, the working distance, and signal mix. This will produce the far more information and lead to a better understanding of samples.

Investigations & Applications

Low Temperature Scanning Electron Microscopy of Snow Crystals

Samples of snow are studied by scanning electron microscopy to determine grain size and morphology at the Beltsville of the U.S. Department of Agriculture. Grain size and morphology are factors in estimating the water content of winter packed snow. Correlation with remote sensing is used for predication of flooding and estimating water supply. Images are in the public domain and available for use with proper citation.
