Product Description
NANOSENSORS? AR10-NCHR AFM tips are designed for non-contact 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.
The probe offers unique features:
length of the high aspect ratio portion of the tip > 1.5 μm
typical aspect ratio at 1.5 μm in the order of 12:1 (when viewed from side as well as along cantilever axis)
excellent tip radius of curvature
highly doped silicon to dissipate static charge
high mechanical Q-factor for high sensitivity
Coating Description
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. As the coating is almost stress-free the bending of the cantilever due to stress is less than 2% of the cantilever length.
