HQ:NSC14/Cr-Au
Gold Coated Soft Tapping Mode AFM Probe
AFM probes of the HQ:NSC14 series are generally used in tapping mode for imaging relatively soft samples to obtain better phase contrast and reduce surface deformations caused by the tapping AFM tip.
The HQ AFM probes offer high consistency of the AFM tip radius, the AFM cantilever reflectivity and the quality factor.
The overall 30 nm Au coating with 20 nm Cr sublayer is electrically conductive and chemically inert. It also ehnances the laser reflectivity of the AFM cantilever in air and liquids. The resulting coated AFM tip radius is below 35 nm. The coating may cause AFM cantilever bending up to 3°.
