JEOL JEM-3200FSC Liquid Helium Cryo-TEM

  • JEM-3200FSC field emission cryo-TEM is equipped with an in-column Omega-type energy filter spectrometer. The microscope combines excellent analytical performance for elemental mapping and zero-loss imaging with high resolution optics. The 300keV field emission gun produces a bright, coherent electron beam for the most demanding quantitative studies. The JEM-3200FSC features a liquid helium cooled cryogenic stage which allows specimen observation below 25K.
