Product Description:
The 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 excellent tip radius and the minimized variation in tip shape provide more reproducible images and enhanced resolution.
NANOSENSORS™ PPP-CONTR AFM probes are designed for contact mode (repulsive mode) AFM imaging. This sensor can also be used for force-distance spectroscopy mode or pulsed force mode (PFM). The PPP-CONTR type is optimized for high sensitivity due to a low force constant.
The probe offers unique features:
- excellent tip radius of curvature
- highly doped silicon to dissipate static charge
- Al coating on detector side of cantilever
- high mechanical Q-factor for high sensitivity

Coating:
The reflex coating is an approximately 30 nm thick aluminum coating on the detector side of the cantilever which enhances the reflectivity of the laser beam by a factor of about 2.5. Furthermore it prevents light from interfering within the cantilever. The virtually stress-free coating is bending the cantilever less than 2% of the cantilever length.
