PPP-LFMR

PointProbe® Plus Lateral Force Microscopy - 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 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 lateral or friction force microscopy NANOSENSORS™ offers a special type of AFM probe (LFM: lateral force microscopy). This sensor type is optimized for a high sensitivity to lateral or friction forces by an extremely soft, thin cantilever

The probe offers unique features:

  • guaranteed tip radius of curvature  < 10 nm
  • tip height 10 - 15 µm
  • highly doped silicon to dissipate static charge
  • Al coating on detector side of cantilever
  • high mechanical Q-factor for high sensitivity
  • alignment grooves on backside of silicon holder chip
  • precise alignment of the cantilever position (within +/- 2 µm) when used with the Alignment Chip
  • compatible with PointProbe® Plus XY-Alignment Series

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