Point Probe AFM tip
NanoWorld® Pointprobe® NCH probes are designed for non-contact or tapping mode imaging. This probe type combines high operation stability with outstanding sensitivity and fast scanning ability.
All SPM and AFM probes of the Pointprobe® series are made from monolithic silicon which is highly doped silicon to dissipate static charge. They are chemically inert and offer a high mechanical Q-factor for high sensitivity. The tip is shaped like a polygon based pyramid with a typical height of 10 - 15 µm.
Additionally, this probe offers typical tip radius of curvature of less than 8 nm.
For applications requiring lower resonance frequencies or a cantilever length exceeding 125 µm we recommend our Pointprobe® type NCLR.
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: Standard
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.
