    • Two methods were used to calculate this figure: the torsional Sader method (Ref.) allows the calculation of the spring constant (in units of newton-metres per radian) for a rectangular cantilever of the same dimensions, but without the crossbar. This may then be converted into a spring constant in newtons per metre by multiplying by the square of the tioffset. This method would be expected to underestimate the spring constant. The cantilever may also be treated as two springs in series. Assuming that there is minimal cross-talk between the torsional and flexural deflection signals, and that the inverse optical lever sensitivity is determined by the geometry of the cantilever, it is possible to calculate the spring constants by taking an approach curve while monitoring the vertical and lateral photodiode signals. Estimates from these two methods are in broad agreement.
