Park SPM Modes
Get the data you need with Park’s selection of scanning modes
Park AFM features a comprehensive range of scanning modes that can collect a wide array of data types accurately and efficiently. From the world's only True Non-Contact™ mode that preserves tip sharpness and sample integrity to advanced Magnetic Force Microscopy, Park Systems offers the most innovative, accurate modes in the AFM industry.
Park Systems offers some of the most innovative standard imaging modes in the AFM industry. Park AFM's True Non-Contact™ mode is the world's only truly non-contact AFM scanning mode while our standard scanning mode is among the most accurate available on the market.
Park AFM features the only true non-contact standard imaging mode. This mode preserves tip sharpness and sample integrity for better and more accurate scans with less minimal maintenance required.
When True Non-Contact™ mode is activated, a piezoelectric modulator vibrates a cantilever at a small amplitude and fixed frequency near the intrinsic resonance of the cantilever. As the tip approaches the sample, the van der Waals attractive force between the tip and sample influences the amplitude and phase of the cantilever's vibration. These amplitude and phase changes are monitored by the patented Z-servo feedback system of the Park AFM series, which also maintains a few nanometers tip-surface distance without damaging the sample surface or tip.
Specifications :Tip-sample distance : 3 nm (typical)
Cantilever oscillation frequency : 1 - 600 kHz
Cantilever oscillation amplitude : 1 - 2 nm (typical)
Phase Imaging with Park AFM provides an accurate measurement of mechanical properties, especially for highly sensitive samples whose topography is best measured using True Non-Contact™ mode. Phase data that contains the mechanical property of the sample is acquired by monitoring the phase lag between the signal that drives the cantilever oscillation and the cantilever oscillation output signal.
