Point Probe AFM tip
NanoWorld® Pointprobe® CONT probes are designed for contact mode imaging. Furthermore this AFM probe can be used for force-distance spectroscopy mode or pulsed force mode (PFM). The CONT type is optimised for high sensitivity due to a low force constant.
All SPM and AFM probes of the Pointprobe® 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 AFM tip is shaped like a polygon based pyramid with a typical height of 10 - 15 µm.
Additionally, this AFM probe offers typical AFM tip radius of curvature of less than 8 nm.
A trapezoidal cross section of the AFM cantilever and therefore 30% wider (e.g. NCH) AFM 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: Standard
Aluminum Reflex Coating
The aluminum reflex coating consists of a 30 nm thick aluminum layer deposited on the detector side of the AFM cantilever which enhances the reflectance of the laser beam by a factor of 2.5. Furthermore it prevents light from interfering within the AFM cantilever.
As the coating is almost stress-free the bending of the AFM cantilever due to stress is less than 2 degrees.
