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

gallery/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
