Park FX40 is Park Systems’ latest innovation in atomic force microscopy (AFM), designed for high-resolution imaging of small samples. With a low noise floor, minimal thermal drift, and enhanced mechanical stability, the FX40 delivers unmatched precision and reliability. Like all Park AFMs, FX40 features an orthogonal scan system and True Non-contact™ mode, enabling accurate, high-resolution metrology, even on the most delicate or fragile samples.​ Key features of FX40 include automatic probe exchange, automatic laser beam alignment, and a sample-view camera; the signatures of FX-series AFMs that streamline operation while significantly enhancing productivity. With the powerful FX AFM controller featuring an 8-channel lock-in amplifier and 5 MHz bandwidth for advanced signal processing, FX40 supports a wide range of cutting-edge modes and options. Built for both precision and ease of use, the FX40 is the ideal solution for nanoscale imaging and analysis.

In this alternative technique to non-contact mode, the cantilever again oscillates just above the surface, but at a much higher amplitude of oscillation. The bigger oscillation makes the deflection signal large enough for the control circuit, and hence an easier control for topography feedback. It produces modest AFM results but blunts the tip’s sharpness at a higher rate, ultimately speeding up the loss of its imaging resolution.
