VIT_P/Pt
| TOP VISUAL NONCONTACT Silicon Cantilevers VIT_P/Pt series |
TOP VISUAL probes are intended:
1. For precise positioning of the tip over the point of interest and for direct real-time observation of sample scanning and modification (nanomanipulation) processes.
2. For precise positioning of a tightly focused laser spot at the tip end - for investigations of optical effects between tip and sample (TERS, TEFS, s-SNOM etc).
