Product Description

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 SPM and AFM 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.

For measurements on samples with sidewall angles approaching 90° we offer specially tailored tips showing a high aspect ratio portion with near-vertical sidewalls.

These probes offer unique features:

• length of the high aspect ratio portion of the tip > 2 µm

• typical aspect ratio of this portion in the order of 7:1 (when      viewed from side as well as along cantilever axis)

• half cone angle of the high aspect ratio portion typically <      5°

• excellent tip radius of curvature

Coating Description

Aluminum Reflex Coating

The aluminum reflex coating consists of a 30 nm thick aluminum layer deposited on the detector side of the cantilever which enhances the reflectance of the laser beam by a factor of 2.5. Furthermore it prevents light from interfering within the cantilever.
