Abstract
We demonstrate that the side lobes of a Bessel function generated by an axicon are suppressed by more than 20 dB over 5 mm depth of focus in a confocal imaging system using a single mode fiber. We also show a rotational image in biological tubular samples with 2.5 µm axial resolution, 8 µm lateral resolution, and 5 mm depth of focus using a custom designed axicon.
