Abstract:
A calibration device is disclosed. A platform has a substantially planar surface suitable for the landing of an AFM cantilever tip, one or more supporting legs arranged to provide sprung resistance to the platform and a capacitive sensor for measuring the combined spring constant of the one or more supporting legs with respect to displacement substantially perpendicular to said substantially planar surface.
