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.

Application
Most of the routine topography imaging experiments require AFM probes of about 8 to 10nm radius. Using these AFM probes, lateral resolution down to 5nm is attainable for scan size below 1μm. Usually, sharpened silicon etched AFM probes are used for general purpose measurements.
