ARROW™ AFM tip
Optimized positioning through maximized tip visibility
NanoWorld® Arrow™ CONT probes are designed for Contact Mode imaging. Furthermore this type can be used for Force Distance Spectroscopy Mode or Pulsed Force Mode (PFM). The CONT type is optimized for high sensitivity due to a low Force Constant.
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.
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
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.
As the coating is almost stress-free the bending of the cantilever due to stress is less than 2 degrees.
