Pelco Dimpler

Pelco Dimpler


This equipment is used to mechanically pre-thin Transmission Electron Microscopy samples prior to Ar+ ion beam thinning to electron transparency.  The tools either “flat” or “dimple” the surface(s) of a 3mm dia disc through a series of grinding and/or polishing steps.  The abrasive material is typically mono or polycrystalline diamond suspension with particle diameters of 0.5-15 µm. 


  • Rapid and controlled mechanical thinning of TEM specimens.
  • Sample diameter = 3mm
  • Max sample thickness 1mm (0.5mm is ideal)
