Nanoindentation and Scratch Testing
Nanoindentation for professionals
In material testing, the dynamic method has increasingly come to complement classic nanoindentation. Analogous to dynamic-mechanical analysis (DMA), it allows testing of the visco-elastic properties of substances. The FISCHERSCOPE® HM2000 determines properties such as the indentation hardness and the depth-dependent elastic modulus – and all of that in the nanometer range!
If you want to measure a sample in multiple places or do automated testing, the FISCHERSCOPE HM2000 is ideal. In just a few clicks, you can program in the measuring points – the instrument takes care of the rest.
In addition to quality testing in electroplating, a common area of application for the FISCHERSCOPE HM2000 is the characterization of polymers at different temperatures. For this purpose, the automated system can be equipped with a heating stage.

High-end technology for challenging measurement tasks
The PICODENTOR® HM 500 combines high-end technology with simple operation. The device is designed for extremely fine instrumented nanoindentation testing and dynamic mechanical analysis. It allows depth-dependent determination of material parameters such as Martens or Vickers hardness and the modulus of penetration.
The HM500’s excellent force and displacement resolution make it possible to analyze coatings in the nanometer range. This provides a level of accuracy usually found only in very complex – and much more expensive – measuring instruments.
Fischer believes in making your work as easy as possible. No matter whether the pieces you have to test have dark surfaces, complex geometries or are very small – just start measuring, no sample preparation required! And with the automated sample stage and powerful microscope, you can program automated tests with just a few clicks.

ADHESION TESTER ST30 AND ST200
Adhesion testers for paints and hard material coatings
Whether the functional coating on a drill bit lasts a long time or a car paint can withstand harsh weather – it all depends on how well the coating adheres to its substrate. Scratch and adhesive tests simulate in the lab the kinds of loads that a surface will normally be exposed to in everyday life.
The FISCHERSCOPE®-ST series is a modular scratch adhesion test system that offers two models to cover different measurement ranges. The ST30 scratches with low force and is ideal for testing soft materials such as paints or polymers, as well as for thin layers as used in the semiconductor industry. For hard coatings, the ST200 uses higher forces.
The resulting scratch is primarily evaluated optically. For this purpose, the FISCHERSCOPE ST has a high-resolution microscope that can be equipped with up to three lenses, as needed. In addition to the optical analysis, it can also measure the acoustic emissions, the tangential force, and the penetration depth.
