Gatan Ilion Ion Polisher

The Gatan Ilion ion polisher allows the preparation of high-quality planar cross sections from difficult samples that do not lend themselves to mechanical polishing or focused ion beam milling. The instrument can perform masked broad ion beam milling, also known as “slope cutting.”

This surface preparation technique utilizes a large (1 mm) ion beam to strip away an extensive, finely polished area for subsequent microscopy and microanalysis. A solid, sputter- resistant shield blocks half of the ion beam, effectively masking the lower half of the beam and creating a lateral sputtering plane that strips away a thin layer of the sample surface. The resulting surface is very flat and usually free of artifacts.
