Product Description

NanoWorld Pointprobe® NCH probes are designed for non-contact or tapping mode imaging. This probe type combines high operation stability with outstanding sensitivity and fast scanning ability.

All SPM and AFM probes of the Pointprobe® series are made from monolithic silicon which is highly doped to dissipate static charge. They are chemically inert and offer a high mechanical Q-factor for high sensitivity. The tip is shaped like a polygon based pyramid with a typical height of 10 - 15 µm.

This tip shows a high aspect ratio portion with near-vertical sidewalls and is specially tailored for measurements on samples with sidewalls approaching 90°.

These probes offer unique features:

  • Length of the high aspect ratio portion of the tip > 2 µm
  • Typical aspect ratio of this portion in the order of 7:1
    (when viewed from side as well as along cantilever axis!)
  • Half cone angle of the high aspect ratio portion typically < 5°
  • Typical tip radius of curvature < 10 nm
A trapezoidal cross section of the cantilever and therefore 30% wider (e.g. NCH) cantilever detector side result in easier and faster laser adjustment. Additionally, because there is simply more space to place and reflect the laser beam, a higher SUM signal is reached.

Coating Description

Aluminum Reflex Coating

The aluminum reflex coating consists of a 30 nm thick aluminum layer deposited on the detector side of the cantilever which enhances the reflectance of the laser beam by a factor of 2.5. Furthermore it prevents light from interfering within the cantilever.
