Conductive AFM

The Optimized Resistance Conductance Amplifier (ORCA™) cantilever holder enables conductive AFM imaging and I-V measurement capabilities. The standard module is capable of measuring currents ranging from ~1 pA to 20 nA. The dual gain version expands the current measurement range to 10 µA.

  • Powerful current sensing technique for electrical characterization of conductivity variations in resistive samples

  • Standard ORCA module measures currents from ~1 pA to 20 nA.

  • Dual Gain ORCA uses two separate amplifiers for current range, from ~6 pA to 10 µA
