NANOSENSORS™ PointProbe® Plus AFM Probes

PointProbe® Plus Rotated Tip Non- Contact / Tapping Mode - High Resonance Frequency - Reflex Coating

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 AFM tip shape. The typical AFM tip radius of less than 7 nm and the minimized variation in AFM tip shape provide more reproducible images and enhanced resolution.

NANOSENSORS™ PPP-RT-NCHR AFM probes are designed for non-contact mode or tapping mode AFM (also known as: attractive or dynamic mode). This AFM probe combines high operation stability with outstanding sensitivity and fast scanning ability.

For certain applications the rotated PointProbe® Plus AFM Tip offers more symmetric imaging. The rotated AFM tip shape is identical to the classic AFM tip shape but it is rotated by 180° degrees with respect to the AFM cantilever beam direction.

The AFM probe offers unique features:

  • guaranteed AFM tip radius of curvature < 10 nm
  • AFM tip height 10 - 15 µm
  • highly doped silicon to dissipate static charge
  • high mechanical Q-factor for high sensitivity

The reflex coating is an approximately 30 nm thick aluminum coating on the detector side of the AFM cantilever which enhances the reflectivity of the laser beam by a factor of about 2.5. Furthermore it prevents light from interfering within the AFM cantilever. The virtually stress-free coating is bending the AFM cantilever less than 2% of the AFM cantilever length.

This AFM probe features alignment grooves on the back side of the holder chip. These grooves fit to the NANOSENSORS Alignment Chip.
