PPP-CONTSCAu

PointProbe® Plus Contact Mode Short Cantilever -Au Coating

The new PointProbe® Plus (PPP) combines the well-known features of the proven PointProbe® series such as high application versatility and compatibility with most commercial SPMs with a further reduced and more reproducible tip radius as well as a more defined tip shape.

The NANOSENSORS™ PPP-CONTSCAu is an alternative cantilever type for contact mode applications. The length of cantilever is reduced with respect to the preferred contact mode type enabling easier exchange with non-contact mode probes for some AFM instruments. Additionally, this probe type allows the application for lateral or friction force mode.

The probe offers unique features:

A metallic layer (gold) is coated on both sides of the cantilever. The tip side coating enhances the conductivity of the tip and allows electrical contacts - the typical tip radius of curvature is less than 50nm. The detector side coating enhances the reflectivity of the laser beam by a factor of 2.5 and prevents light from interfering within the cantilever. The coating process is optimized for stress compensation. The bending of the cantilever due to stress is less than 3.5% of the cantilever length.

Please note: Wear at the tip can occur if operating in contact-, friction- or force modulation mode.
