HQ:NSC19/Cr-Au
Gold Coated Soft Tapping Mode and LFM AFM Probe
AFM probes of the HQ:NSC19 series combine relatively high resonance frequency and low force constant, which makes them suitable for imaging soft and fragile surfaces at relatively high speeds in Soft tapping mode. They are not designed as dedicated ScanAsyst®* mode AFM probes, but they have been confirmed as compatible with Bruker ScanAsyst® PeakForce Tapping™* mode by many customers all over the world. These AFM probes are also used in Lateral force microscopy due to their high sensitivity to lateral forces.
The monolithic silicon HQ AFM probes offer high consistency of the AFM tip radius, cantilever reflectivity and 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°.
