Highest flexibility combined with extreme performance

The NanoWizard® 4 XP NanoScience atomic force microscope delivers atomic resolution and a large scan range of 100 µm in one system. It enables fast scanning with rates of up to 150 lines/sec and seamless integration with advanced optical techniques. A wide range of modes and accessories for environmental control, mapping of nanomechanical, electrical, magnetic or thermal properties, makes it the most flexible system available on the market today.

The NanoWizard 4 XP NanoScience is equipped with a range of new features, including:

  • PeakForce Tapping® for easy imaging
  • Fast Scanning option with up to 150 lines/sec
  • NestedScanner Technology for high-speed imaging of surface structures up to 16.5µm with outstanding resolution and stability
  • New tiling functionality for automated analysis of large sample areas
  • V7 Software with revolutionary new workflow-based user interface
  • DirectOverlay™ 2 software for perfect integration and data correlation with advanced fluorescence microscopy platforms
  • Vortis™ 2 controller for high-speed signal processing and lowest noise levels

PeakForce Tapping provides superior force control and an uncomplicated setup, no matter what the sample or environment. No expert knowledge or cantilever tuning is necessary. It enables precise control of probe-to-sample interactions and minimizes imaging forces, thereby protecting your tip and ensuring consistent, long-term, high-resolution imaging.

Automated analysis of large sample areas with new tiling functionality

The fastest and easiest way to navigate is to see where you want to go. DirectOverlay 2 provides instant navigation, with direct selection of measurement positions anywhere within the scanner range. The Motorized Precision Stage and HybridStage™ free experiments of the lateral constraints of the AFM piezo range, and allow direct motorized movement to selected positions.

The new DirectTiling feature automatically creates a large optical overview to accelerate this process. Multiscan enables tiling of high-resolution images to build up a comprehensive overview of the sample. Repetitive or complicated measurement sequences can be automated using ExperimentPlanner™ macros.

Four square regions are marked with a concentric corner pattern, the inner corners form a 50 micron square with test patterns printed in the center, but not visible in the optics. Imported into the SPM software with DirectOverlay, such images allow single-click navigation between reference positions separated by many times the piezo range.

Enhanced mapping of material properties

KPM on SRAM EFM on SRAM CAFM on CU conduct layer The characterization of electrical, electromechanical or magnetic sample properties was always a difficult task, in particular on loosely attached, brittle or soft samples. JPK's QI™-Advanced mode capabilities make this easy and straight forward. The NanoWizard 4 XP NanoScience system is supported by a comprehensive range of modes and accessories, each designed for easy handling and to meet the individual needs of researchers. Many experiments investigating material properties, including electrical properties, benefit from working in an enclosed cell to measure under a controlled inert gas atmosphere.
