Abstract
The design of a Reflection-Mode aperture SNOM(R-SNOM) with macroscopic collection of the reflected light is presented. This instrument incorporates a Shear-Force feedback mechanism, and also works as an STM, in which case it exhibits lateral resolution of 2–3nm. The light at 685nm is coupled into a tapered and metallised single-mode optical fibre. It is then reflected from the sample, collected using a microscope objective, and detected using a PMT. The detection of the Shear-Force signal is based on shadowing of a laser beam by an oscillating fibre. Some initial studies of Shear-Force are presented, along with the first scanning optical images obtained.
