 Type: NCL |
| Non-contact / Tapping™ mode - Long Cantilever |
|
|
NanoWorld Pointprobe® NCL probes are designed for non-contact or tapping™ mode imaging and offer an alternative to our high frequency non-contact type NCH. The NCL type is recommended if the feedback loop of the microscope does not accept high frequencies or if the detection system needs a minimum cantilever length (> 125 µm). This probe combines high operation stability with outstanding sensitivity. Compared to the high frequency non-contact type NCH the maximum scanning speed is slightly reduced.
All 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 tip is shaped like a polygon based pyramid with a height of 10-15 µm.
Additionally this probe offers typical tip radius of curvature of less than 8 nm. |

For applications allowing higher resonance frequencies or a shorter cantilever length we recommend our Pointprobe® type NCH. For more information contact: info@nanoworld.com | |
