The Idea of Nanoindentation
In Nanoindentation, a sample is indented with a small diamond tip (tip radius some nm).
In situ Nanoindentation can give more information on the formation and propagation of mechanically induced dislocations and defects during the experiment.
The In Situ Nanoindenters are compact, robust, versatile and can be fitted to various kinds of microscopes such as Scanning Electron Microscopes (SEM), light microscopes, Synchrotron beamlines, and many more. The idea of nanoindentation arose from the realization that an indentation test is an excellent way to measure very small volumes of materials.

Experimental Aspects
• Successfully address metrology challenges like Mechanical Strength (Elastic Modulus, Hardness, Fracture), Interfacial Adhesion and Failure
• Characterization of microstructural changes with sub-nanometer resolution in an in-situ vacuum environment
• Characterizing the mechanical properties of surfaces or structures IN-SEM and IN-AIR
• Characterization of organic, inorganic, soft or hard materials and coatings
• Nanomechanical characterization with direct observation

Understanding material behavior at the micro-ａnd nano-scale

• Compact and robust design in a stand-alone instrument that is easy to install and remove and which can operate in any position(horizontal, vertical or tilted).
