True Tapping Mode Scanning Near-Field Optical Microscopy with Bent Glass Fiber Probes

Figure 1

Illustrating the geometry of the bent fiber. (a) The following sizes of the bent fiber probe are shown: , bending angle; , bending radius; , fiber diameter; , length of the fiber from the point at which it is rigidly fixed until the bent sector; , length of the probe’s free part. (b) You can see the photo of a real bent fiber attached to the TF; here α ≈ 90°, ≈ 300 μm,  μm,  mm, and  μm. Thin glass fiber-made driving rod connecting the probe with one of the TF’s prongs is shown with a red arrow.
