Upgrade Options



The TriboScope nanomechanical test instrument utilizes an in-situ Scanning Probe Microscopy (SPM) imaging capability to realize the benefits of SPM imaging and quantitative nanoindentation in a single system. The synergy offered by interfacing the industry-leading sensitivity of the Hysitron transducer to an SPM provides superior testing capabilities previously unavailable to the materials characterization community.

Quantitative Results

The design of the Hysitron transducer allows it to be fitted to any commercially available SPM via a simple, temporary modification.

This involves a replacement of the normal detector head with the Hysitron transducer, in which the transducer serves the function of sensing the surface and providing topographic feedback for imaging. However, the TriboScope/SPM system is also then capable of quantitative nanomechanical testing. It is this synergy that makes this system the most sensitive and stable instrument on the market. The indenter utilizes a rigid probe that makes the quantification of the force and displacement measurements more reliable than a measurement made with a probe on the end of a cantilever, which introduces many uncertainties. The TriboScope combines nanoNewton force sensitivity and picometer displacement resolution with SPM imaging for a powerful tool to aid in material studies from basic research to product development to quality control.

In-situ SPM Imaging

In-situ SPM imaging allows the indenter probe to be positioned within ten nanometers of any desired feature or phase of a material.

After the test is performed, an image of the deformation caused by the test can be obtained immediately by using the indenter tip to scan the surface. This eliminates the need to reposition an imaging instrument over the testing site. The force and displacement results that are acquired during the test, in conjunction with the in-situ image, offer an unparalleled wealth of information concerning the mechanical properties of the material. Insitu imaging is a necessary tool to yield the repeatable precision necessary for meaningful results in nanoscale testing.
