Discover the Gatan Precision Etching & Coating System (PECS II)


The new PECS II system is the answer to challenges in SEM specimen preparation such as:

  • Debris and contamination from mechanical or electrochemical polishing
  • Large surface areas
  • Need for clean and uniform coating after polish, without breaking vacuum
  • Minimize preferential etching due to sample chemistry or hardness differences

The new PECS II features:

  • Low energy (range: 0.1 to 8.0 keV) ion polishing leaves neither debris nor contamination (minimal Ar ion implantation)
  • Large surface areas, up to 4 mm (yes, 4,000 µm!) radius
  • Polish and coat with a single pump down
  • No mechanical deformation, no chemical reactions, minimum preferential etching thanks to low glancing angle (±10°)
  • Options for liquid nitrogen cooling and digital zoom camera

The new PECS II is ideal for applications where a smooth, clean, uniform surface is essential:
  • EBSD mapping
  • Cathodoluminescence experiments
  • Minimize topography contrast on cross sections
  • Materials sensitive to oxygen or humidity
