PPP-NCSTAuD
PointProbe® Plus Non-Contact / Soft Tapping Mode - Au Coating (Detector side)
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 typical tip radius of less than 7 nm and the minimized variation in tip shape provide more reproducible images and enhanced resolution.
NANOSENSORS™ PPP-NCSTAuD AFM probes are designed for non-contact or soft tapping mode imaging. The combination of soft cantilever and fairly high resonance frequency enables stable and fast measurements with reduced tip-sample interaction. This feature significantly reduces tip wear and sample wear at the same time.
- The probe offers unique features:
- - guaranteed tip radius of curvature < 10 nm
- highly doped to dissipate static charge
- Au coating on detector side of cantilever
- chemically inert - A metallic layer (Au) is coated 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.
