How to choose an AFM probe
SCM
For optimal performance with our AFM systems please request a quote from Park Systems. Mounted cantilevers are additionally tested. All probes that are not listed here from Adama Innovations, Applied Nano Structures, Inc, BudgetSensors, MikroMasch, Nanosensors™, Nanotools GmbH, Nanoworld AG, NuNano, Olympus Corp., are possible to order from our probe store. Probes from other manufacturers also can be possible to order upon request for quotation. The performance of probes ordered from other sources are not guaranteed.

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 more reproducible tip radius as well as a more defined tip shape. The minimized variation in tip shape provides more reproducible images. The PPP-EFM probe is offered for electrostatic force microscopy. An overall metallic coating (PtIr5) on both sides of the cantilever increasing the electrical conductivity of the tip. The force constant of this type is specially tailored for the electrostatic force microscopy yielding very high force sensitivity while simultaneously enabling tapping mode and lift mode operation.
