High Aspect Ratio (> 5:1) - Non-Contact/Tapping Mode - Long Cantilever - Reflex Coating

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) half cone angle at 2 µm of the high aspect ratio portion typically < 5° guaranteed tip radius of curvature < 15 nm highly doped silicon to dissipate static charge high mechanical Q-factor for high sensitivity alignment grooves on backside of silicon holder chip precise alignment of the cantilever position (within +/- 2 µm) when used with the Alignment Chip compatible with PointProbe® Plus XY-Alignment Series

NANOSENSORS™ AR5-NCLR 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 (Focused 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.
