Nanoindentation is a process characterized by the continuous measurement of the force applied to and the resulting displacement of a sample. Commercial indenters are cost-prohibitive; therefore, a low-cost module using a unique inverse method of nanoindentation was developed. Using this method, the force and displacement data are obtained indirectly from the interferometer images. A final design was selected, analyzed, and constructed. Lastly, a series of indentation events were performed, validating both the mechanism and the approach to nanoindentation.
