Description
Sharpened glass fiber – made probes attached to a quartz tuning fork exploiting the shear force–based feedback is the most popular in the field of SNOM. The use of tapping mode feedback could be preferable. Here we report such an approach realized via bent fiber probes. Detailed analysis of the vibration mode shows that an extreme caution is needed for the realization truly tapping mode. Bent probes were attached to the TF in double resonance conditions enabling to achieve very large quality factor. The performance of these probes is demonstrated. The next step is the testing of this probes in liquid.
