Type: NCHR
Non-contact / Tapping™ mode -
High resonance frequency - Reflex coating
NanoWorld Pointprobe® NCH probes are designed for non-contact or tapping™ mode imaging. This probe type combines high operation stability with outstanding sensitivity and fast scanning ability.
All probes of the Pointprobe® series are made from monolithic silicon which is highly doped to dissipate static charge. They are chemically inert and offer a high mechanical Q-factor for high sensitivity. The tip is shaped like a polygon based pyramid with a height of 10-15 µm.

Additionally this probe offers typical tip radius of curvature of less than 8 nm.

The reflex coating on the detector side of the cantilever enhances its reflectivity and prevents light from interfering within the cantilever.

Reflex Coating
Reflex coating is an approximately 30 nm thick aluminium coating on the detector side of the cantilever which enhances the reflectivity of the laser beam by a factor of 2.5. Furthermore it prevents light from interfering within the cantilever.

For applications requiring lower resonance frequencies or a cantilever length exceeding 125 µm
we recommend our Pointprobe® type NCLR.
