Type: Arrow™ FMR

Force Modulation Mode - Reflex Coating

Optimized positioning through maximized tip visibility NanoWorld Arrow™ FM probes are designed for Force Modulation Mode imaging. The Force Constant of the FM type fills the gap between Contact and Non-Contact probes. Furthermore Non-Contact / TappingMode™ imaging is possible with this AFM probe. All probes of the Arrow™ series are made from monolithic silicon which is highly doped to dissipate static charge. They are chemically inert and offer a high mechanical Q-factor for high sensitivity. The probes feature a rectangular cantilever with a triangular free end and a tetrahedral tip with a height of 10 - 15 µm. Additionally this probe offers a typical tip 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 on the detector side of the cantilever enhances its reflectivity and prevents light from interfering within the cantilever.

Reflex Coating

Reflex coating is an approximately 30 nm thick aluminium coating on the detector side of the cantilever which enhances the reflectivity of the laser beam by a factor of 2.5. Furthermore it prevents light from interfering within the cantilever.
