The new XY-auto alignment probes for Non-Contact / Tapping mode application (High resonance frequency) extend the well-known plug-and-fit auto alignment concept of the Alignment Chip (ALIGN) to 125 µm short cantilevers optimized for high speed non-contact / Tapping mode applications. If the alignment chip is mounted to the AFM head probe exchange is possible with a tip repositioning accuracy of better than ± 8 µm.
As a matter of course, the features of the provenPoint Probe® Plus series such as high application versatility, compatibility with most commercial SPMs, extremely low and reproducible tip radius as well as a precisely defined tip shape are maintained. 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-XYNCSTR 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
- Al coating on detector side of cantilever
- chemically inert
- high mechanical Q-factor for high sensitivity
- tip repositioning accuracy of better than ± 8 µm (in combination with Alignment Chip)
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 3.5% of the cantilever length.
