AR5-NCHR

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

NANOSENSORSAR5-NCHR AFM tips are designed for non-contact mode or tapping mode AFM. This probe 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.
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)
- (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 to dissipate static charge
- high mechanical Q-factor for high sensitivity
The reflex coating is 30 nm thick aluminum coating on the detector side of the cantilever which enhances the reflectivity of the laser beam by a factor of about 2.5. Furthermore it prevents light from interfering within the cantilever. The virtually stress-free coating is bending the cantilever less than 2% of the cantilever length.
