There is a rather informative entry on Wikipedia (Click Here) detailing the Low Voltage Electron Microscopy (LVEM) technique. The entry goes through the advantages and limitations of the technique. The most notable advantages of LVEM are increased contrast, the elimination of the heavy metal staining procedure, and the ability to have TEM, SEM and STEM in the same instrument. We are proud to say that the LVEM5 is currently the only Low Voltage Electron Microscope available commercially today.
