Performance without compromise
The DriveAFM is Nanosurf’s novel flagship AFM platform: a tip-scanning atomic force microscope (AFM) that combines, for the first time, several capabilities in one instrument to enable novel measurements in materials and life sciences. The DriveAFM overcomes drawbacks of other tip-scanning instruments and provides atomic resolution together with fast scanning, fast force spectroscopy, and large scan sizes up to 100 µm. Thanks to Nanosurf’s innovations in optical beam path engineering and scanner design, the Drive scan head features photothermal actuation and full motorization for superior research performance and is easy to use for researchers at all levels of experience.
- CleanDrive: stable excitation in air and liquid
- Ultra-low noise
- Direct drive: high-resolution imaging and large scan area
- Fully motorized system: full control via software
