Sphere-based cantilever for SNOM — •Critian Gonzalez Mora, Daniela Bayer, Elena A. Ilin, Egbert Oesteschulze, and Martin Aeschlimann — University of Kaiserslautern Erwin Schroedinger Str. 46 D-67663, Kaiserslautern

We present the development and first measurements with a new kind of cantilever sensors, which allow an enhanced transmission of light keeping the possibility to perform SNOM (Scanning Near-field Microscope) measurements in contact to the sample.

The characterization performed my measuring Au Nano-rings show a clear polarization dependence for the excited plasmons. These new cantilevers are a modification of the traditional aperture cantilevers for aperture based SNOM and consist, basically, of a glass micro-sphere at the apex of the tip of the sensor.
