The Nanowizard3 The Most Flexible, High Resolution AFM With True Optical Integration — •Gerd Behme — JPK Instruments, Berlin, Deutschland

The NanoWizard3 represents the latest in AFM technology. The new Vortis controller series uses the latest FPGA architecture to guarantee highest digital performance. Fast signal acquisition and control, advanced feedback and analysis are key components of a modular and ultra flexible controller. The high-speed data acquisition makes the controller perfect for time resolved force spectroscopy, higher harmonics imaging or high frequency cantilever use. Cantilever calibration by thermal noise method up to 3.25 MHz is unique. HyperDrive is a soft sample imaging technique in liquid which provides sub-nanometer lateral resolution with minimal tip-sample interactions and works with off-the-shelf cantilevers. This is made possible by the new optics and electronics of the NanoWizard3 AFM head, which gives the lowest noise level in the cantilever deflection detection system available commercially. The NanoWizard3 maximizes stability, performance and ease of handling for samples in fluid and for full integration with optical microscopy. This enables the simultaneous acquisition of high quality AFM images with optical imaging, under physiological conditions. The unique DirectOverlay software for the JPK NanoWizard systems uses the tip location to calibrate accurately the optical images and integrate them into the AFM software for direct AFM navigation. In addition, exact, quantitative correlation of AFM and optical features is possible.
