Type: SSS-NCL
SuperSharpSilicon - Non-contact / Tapping™ mode -
Long Cantilever
NanoWorld Pointprobe® NCL probes are designed for non-contact or tapping™ mode imaging and offer an alternative to our high frequency non-contact type NCH. The NCL type is recommended if the feedback loop of the microscope does not accept high frequencies or if the detection system needs a minimum cantilever length (> 125 µm). This probe combines high operation stability with outstanding sensitivity. Compared to the high frequency non-contact type NCH the maximum scanning speed is slightly reduced. All probes of the PointprobeŽ 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 enhanced resolution of nanostructures and microroughness we have developed an advanced tip manufacturing process leading to unrivalled sharpness of the SuperSharpSilicon tip.

This probe offers unique features:

  • Typical tip radius of curvature of 2 nm
  • Guaranteed tip radius of curvature 5 nm (yield >80%)
  • Half cone angle < 10° at the last 200 nm of the tip

    For applications allowing higher resonance frequencies or a shorter cantilever length
    we recommend our PointprobeŽ type SSS-NCH.
