NANOSENSORS™ screencast on the service for Calibration for AFM Cantilevers, presented by Wolfgang Engl.
Accurately determined cantilever properties are very important for quantitative force measurements. Force constant and resonance frequency are determined either by thermal tune, the Sader- or the dimensional method, respectively. Usually, the thermal tune method delivers the most precise values, but suffers from the fact that the AFM tip has to get in contact to the urface to calibrate the photo-detector sensitivity. This procedure may damage or break the tip!
NANOSENSORS™ offers a thermal tune calibration procedure performed by Laser vibrometry. This method is contact free and therefore does no damage the tip, but preserves the original AFM tip quality. To ensure the highest level of accuracy NANOSENSORS™ cantilever calibration method is calibrated with a standard, certified by the national German metrology institute.
