PointProbe® Plus Contact Mode

The new PointProbe® Plus (PPP) combines the well-known features of the proven PointProbe® series such as high application versatility and compatibility with most commercial SPMs with a further reduced and more reproducible tip radius as well as a more defined tip shape. The typical tip radius of less than 7 nm and the minimized variation in tip shape provide more reproducible images and enhanced resolution.
NANOSENSORS™ PPP-CONTR AFM probes are designed for contact mode (repulsive mode) AFM imaging. This AFM probe can also be used for force-distance spectroscopy mode or pulsed force mode (PFM). The PPP-CONTR type is optimized for high sensitivity due to a low force constant.

The probe offers unique features:
  • guaranteed tip radius of curvature < 10 nm
  • tip height 10 - 15 µm
  • highly doped silicon to dissipate static charge
  • chemically inert
  • high mechanical Q-factor for high sensitivity
