Principles of surface science and engineering are applied to determine scanned probe microscope cantilever spring constants. The bi-component gold-ceramic cantilever composition is modeled analytically. Finite element analysis is applied to simulate deflection behavior of the probe tip. Data from experimental determination of resonant frequency are employed to infer material characteristics. Combination of the results from these three procedures is employed to infer material characteristics. Combination of the results from these three procedures is used to produce a spring constant assessment within 10% of actual values. An additional convenient program for assessment of scanning probe microscopy cantilever spring constants is developed for rapid estimation with 20% accuracy.
