Online Calibration

Normal spring constant
Torsional spring constant

To use these Java applets to perform an online calibration of the normal and torsional spring constants of rectangular AFM cantilevers, just enter the length and width (in microns), the appropriate fundamental resonant frequency (in kHz) and the corresponding quality factor, and press the calculate button.
