NanoWorld PointProbe®FM probes are designed for force modulation mode imaging. The force constant of the FM type fills the gap between contact and non-contact probes. Furthermore non-contact or tapping™ mode imaging is possible with this AFM probe. 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.
Additionally this probe offers excellent tip radius of curvature.
