HQ:NSC16/Hard/Al BS
Long Scanning, DLC Hardened Tapping Mode AFM Probe with Long AFM Cantilever
AFM probes of the HQ:NSC16 series have AFM cantilevers with a high spring constant and low resonance frequency (below 250 kHz) that can be used in tapping mode in SPMs with low-frequency feedback loops. These AFM probes also fit SPM systems that do not support short AFM cantilever arms.
The HQ AFM probes offer high consistency of the AFM tip radius, the AFM cantilever reflectivity and the quality factor.
A 20 nm wear-resistant DLC coating is applied to the tip side of the AFM cantilever. The coating is chemically inert and more hydrophobic than silicon with a natural oxide layer. The aluminum reflective coating enhances the laser reflectivity of the AFM cantilever by approximately 2.5 times.
