Commercially introduced in 2004, NanoWorld Arrow™ UHF probes have a cantilever capable of resonating with a frequency of up to 2 MHz.
These probes combine outstanding sensitivity with fast scanning ability.
As for all probes of the Arrow™ series, the Arrow™ UHF probes are made from monolithic silicon which is highly doped to dissipate static charge. It is chemically inert and offers a high mechanical Q-factor for high sensitivity.
The Arrow™ UHF probes feature a 35 µm long triangular cantilever and a tetrahedral tip with a height of 3 µm and a radius of curvature smaller than 10 nm.
The unique Arrow™ shape with the tip position at the very end of the cantilever allows easy positioning of the tip on the area of interest.
The reflex coating (aluminum or gold) on the detector side of the cantilever enhances the reflectance of the laser beam by a factor of 2.5 and prevents light from interfering within the cantilever.
