Atom Probe

Imago Local Electrode Atom Probe
Advanced atom probe instrument combining high speed acquisition and large field of view. For analysis of conducting and semiconducting materials.

  • Acquisition rate up to 107 ions per hour.
  • 106 - 3 x 107 atoms per specimen (typ.)
  • Analysis volume: 50 x 50 x 100nm (typ.)
  • Spacial resolution: 0.5nm
  • Mass resolution: 500

Imago Wide-Field-Of-View Laser Atom Probe (LEAP3000)
The new pulsed-laser system allows the 3D analysis of composition and structure at atomic resolution in non-conductive systems such as ceramics, semiconductors, organics, glasses, oxide layers and even biological materials.

Example image:
Three-dimensional atom probe image showing the layered spinodal nanostructure in a new ferrous intermetallic alloy. The solid volumes represent isoconcentration surfaces (i.e., surfaces of constant concentration) of the element nickel, indicating regions of the first spinodal phase. Sandwiched between two of these volumes are atoms of manganese and iron, which concentrate in the second spinodal phase.
