AFM Probe Type: AR5-NCL

Product Description:

NANOSENSORS™ AR5-NCL AFM tips are designed for non-contact or tapping mode AFM. The NCL probe is designed for SPM systems requiring a minimum cantilever length > 125 µm or a resonance frequency of less than 400 kHz. Compared to the high frequency non-contact type NCH the maximum scanning speed is slightly reduced. This cantilever type combines high operation stability with outstanding sensitivity and fast scanning ability.

For measurements on samples with sidewall angles approaching 90° NANOSENSORS™ produces specially tailored tips. These tips are FIB (Forced Ion Beam) milled to achieve a high aspect ratio portion better than 5:1 at the end of the common silicon tip. This subtractive method of producing the high aspect ratio needle offers the advantage of high lateral stiffness and rigidity of the tip.

 
    The probe offers unique features:
        - length of the high aspect ratio portion of the tip > 2 µm
        - typical aspect ratio at 2 µm in the order of 7:1 (when viewed from side as well as along
          cantilever axis)
        - excellent tip radius of curvature
        - monolithic tip
        - highly doped to dissipate static charge
        - high mechanical Q-factor for high sensitivity
        - precise alignment of the cantilever position (within +/- 2 µm) in conjunction with the usage
          of the alignment chip
        - compatible with PointProbe^® Plus XY-Alignment Series

This product features alignment grooves on the backside of the holder chip.
