Soft ResiScope Mode

True Quantitative Resistance/ Current Measurements with Intermittent Contact

Principle

The Soft ResiScope principle is based on intermittent contact. The lack of friction and the constant force of the tip on the sample provide quantitative measurements without damaging the surface of delicate samples.

This unique and innovative AFM mode is able to expand the fields of applications of the « ResiScope II » to soft samples such as organic solar cells, conducting polymers or other biological samples, while retaining its wide measuring range (10 decades).

  • Unique Technology
  • NO Friction
  • Constant Force = Quantitative Electrical Measurements
