Non-contact / Tapping™ mode - High resonance frequency - Reflex coating |
|
|
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 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. The reflex coating on the detector side of the cantilever enhances its reflectivity and prevents light from interfering within the cantilever. |

| Reflex Coating |
|
| Reflex coating is an approximately 30 nm thick aluminium coating on the detector side of the cantilever which enhances the reflectivity of the laser beam by a factor of 2.5. Furthermore it prevents light from interfering within the cantilever. |

For applications requiring lower resonance frequencies or a cantilever length exceeding 125 µm we recommend our Pointprobe® type NCLR. For more information contact: info@nanoworld.com | |
