AFM cantilevers of the 16 series with high spring constant and low resonance frequency (below 250 kHz) can be used in tapping mode in SPM that has a low-frequency feedback loop. These AFM cantilevers also fit SPM systems that do not support AFM probes with short lever arms.
A wear-resistant coating with thickness 20 nm is applied to the tip side of the AFM cantilever. The coating is chemically inert and more hydrophobic than Si with natural oxide layer.
This AFM probe features alignment grooves on the back side of the holder chip.
