PPP-RT-CONTR
PointProbe® Plus Rotated Tip Contact Mode - 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.
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 CONTR type is optimized for high sensitivity due to a low force constant.
For certain applications the rotated PointProbe® Plus Tip offers more symmetric imaging. The rotated tip shape is identical to the classic tip shape but it is rotated by 180° degrees with respect to the cantilever beam direction.

- The probe offers unique features:
- - guaranteed tip radius of curvature < 10 nm
- - highly doped to dissipate static charge
- - high mechanical Q-factor for high sensitivity
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.
