Type: AR10-NCHR
High Aspect Ratio (> 10:1) - Non-contact/Tapping™ mode -
High resonance frequency - Reflex coating
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 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 height of 10 -15 µm.

For measurements on samples with sidewall angles approaching 90° we offer specially tailored tips showing a high aspect ratio portion with near-vertical sidewalls.

These probes offer unique features:
  • Length of the high aspect ratio portion of the tip > 1.5 µm
  • Typical aspect ratio of this portion in the order of 12:1
    (when viewed from side as well as along cantilever axis !)
  • Half cone angle of the high aspect ratio portion typically < 2.8°
  • Typical tip radius of curvature < 10 nm
The reflex coating on the detector side of the cantilever enhances its reflectivity and prevents light from interfering within the cantilever.

Reflex Coating
Reflex coating is an approximately 30 nm thick aluminium coating on the detector side of the cantilever which enhances the reflectivity of the laser beam by a factor of 2.5. Furthermore it prevents light from interfering within the cantilever.
