kLever - Cantilever Calibration Software
KLever uses the plan view dimensions of an AFM cantilever to calculate the normal and torsional spring constant in air without knowledge of their density distribution, thickness or resonant frequency in vacuum using the unloaded resonance technique of Sader et al. [J. E. Sader, J. W. M. Chon, and P. Mulvaney, Rev. Sci. Instrum. 70, 3967 (1999)].
Extendable cantilever database
Input parameters
- Length
- Width
- Quality factor (Q)
- Resonant frequency (fr)
- air pressure
- air temperature
- reads thermal noise spectrum or amplitude spectrum without excitation
Output
- normal & torsional spring constant
- comparison with tolerance range
- Optionally: quality factor (Q) & resonant frequency (fr), when provided with a thermal noise spectrum
