PointProbe® Plus XY-alignment Contact Mode Reflex Coating
The XY-auto-alignment probes for Contact mode application with a Reflex coating extend the plug-and-fit alignment concept of the Alignment Chip (ALIGN) to 450 µm long cantilevers optimized for contact mode applications. Probe exchange with a tip repositioning accuracy of better than ± 8 µm is possible for all probes of the XY-alignment probes series - independent of their cantilever length. This series is adjusted to the tip position of probes with a cantilever length of 225 µm.
As a matter of course, the features of the proven Point 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-CONTR AFM probes are designed for contact mode (repulsive mode) AFM imaging. This AFM probe can also be used for force-distance spectroscopy mode or pulsed force mode (PFM). The CONT type is optimized for high sensitivity due to a low force constant.
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
chemically inert
high mechanical Q-factor for high sensitivity
tip repositioning accuracy of better than ± 8 µm (in combination with Alignment Chip)
