AR10T-NCHR

High Aspect Ratio (> 10:1, Tilted 13°) - Non-Contact/Tapping Mode - High Resonance Frequency - Reflex Coating

NANOSENSORS™ AR10T-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 10:1 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.

On the model AR10T the last 1.5 µm of the tip are tilted 13° to the center axis of the cantilever. With this feature the tilt angle of the cantilever caused by the mount of the AFM head (commonly 13°) will be compensated. Now, nearly vertical sidewalls can be measured offering a symmetrical scan.

The probe offers unique features:

The reflex coating is an approximately 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.
