Arrow UHF

Commercially introduced in 2004, NanoWorld Arrow™ UHF probes are 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 of less 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 (thin aluminum layer*) 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.
