Tapping Mode AFM Probes
Tapping Mode AFM Probes
AFM probes with stiff AFM cantilevers for tapping or non-contact mode

Typical radius of uncoated AFM tip

The HQ:NSC and HQ:XSC AFM tips have trihedral shape with a full cone angle of 40° and even smaller at the last 200nm of the AFM tip apex. The standard tapping mode AFM probes feature stiff AFM cantilevers with high resonance frequencies and force constants above 40N/m. These AFM probes are generally used for imaging hard samples where high topographic and phase contrast are needed. They are also suitable for non-contact mode operation.
The optional aluminum reflective coating enhances the laser reflectivity of the AFM cantilever by approximately 2.5 times.
There is a range of available AFM cantilever coatings for the tip side and back side. Please check the other catalog categories for coated versions of the standard tapping mode AFM probes.
The highly successful HQ series now extends over all AFM probe series with 1, 3 and 4 AFM cantilevers.
