Fig. 3: Optical setup used for the NTA experiments (detailed description in the main text).

From: 3D nanoprinted fiber-interfaced hollow-core waveguides for high-accuracy nanoparticle tracking analysis

Fig. 3

The right inset shows a selected image with five tracked nanoparticles (mean diameter: 100 nm). The left inset shows the orientation of the PMF with respect to the polarization of the input light (double arrow). The lower part of the figure shows (right) a microscopic side view of the fiber-interfaced HCW and (left) the orientation of the HCW relative to the PMF. The tracking experiments were performed in the red area
