PointProbe® Plus SEIKO microscopes - Non-Contact /Tapping Mode High Force Constant

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.

For owners of a Seiko Instruments microscope using the non-contact mode we recommend NANOSENSORS™ PPP-SEIH AFM probes (Seiko Instruments / high 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
This AFM probe features alignment grooves on the back side of the holder chip. These grooves fit to the NANOSENSORS Alignment Chip.
