NanoWorld Pointprobe® NCSTR AFM probes are designed for non-contact or soft tapping mode imaging. The combination of soft cantilever and fairly high resonance frequency enables stable and fast measurements with reduced tip-sample interaction. Thus, tip and sample wear could be significantly decreased.
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 a typical tip radius of curvature of less than 8 nm.
The reflex coating on the detector side of the cantilever enhances its reflectance and prevents light from interfering within the cantilever.
