Product Description:

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 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.

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 > 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°
        - excellent tip radius of curvature
