PPP-CONTSCR

PointProbe® Plus Contact Mode Short Cantilever - Reflex 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 typical tip radius of less than 7 nm and the minimized variation in tip shape provide more reproducible images and enhanced resolution.
The NANOSENSORS™ PPP-CONTSCR 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:

guaranteed tip radius of curvature < 10 nm

tip height 10 - 15 µm

highly doped silicon to dissipate static charge

Al coating on detector side of cantilever

high mechanical Q-factor for high sensitivity

alignment grooves on backside of silicon holder chip

precise alignment of the cantilever position (within +/- 2 µm) when used with the Alignment Chip

compatible with PointProbe® Plus XY-Alignment Series
