Product Description

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 SPM and AFM 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. These probes feature a rectangular cantilever with a triangular free end and a tetrahedral tip with a typical height of 10 - 15 µm.

Additionally, this probe offers a 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.

Image A trapezoidal cross section of the cantilever and therefore 30% wider (e.g. NCH) cantilever detector side result in easier and faster laser adjustment. Additionally, because there is simply more space to place and reflect the laser beam, a higher SUM signal is reached.

Tip shape: Arrow

Coating: Reflex Aluminum

Aluminum Reflex Coating

The aluminum reflex coating consists of a 30 nm thick aluminum layer deposited on the detector side of the cantilever which enhances the reflectance of the laser beam by a factor of 2.5. Furthermore it prevents light from interfering within the cantilever.
