Parabolic Mirror–Assisted Gap-Mode Optical Ultramicroscopy

ByD. Zhang, A. J. Meixner

In this chapter we give an introduction to scanning near-field gap-

mode microscopy. Our goal is to develop an intuitive picture of

this young and fascinating microscopy technique; as well as to

discuss the simultaneously obtained topography and optical signal

that allow us to extract spectroscopic information with nanometer

spatial resolution and sensitivity down to the single-molecule

level.
