Photoconductive measuring tip, measuring setup and use of the photoconductive measuring tip and / or the measuring setup

摘要

The invention relates to a photoconductive measuring tip for field detection of the electrical component of an electromagnetic field, with an arrangement of at least one carrier and a laterally extending on the carrier arranged, mutually insulated first electrode and second electrode, via a photoconductive material in the region of a photoconductive gap a lateral end structure of the first and second electrodes, non-wavelength-adjusted with respect to a wavelength of the electrical component of the electro-magnetic field to be detected, and at least in a front region of the arrangement comprising the front end of the electrodes reduced dimension, wherein a measure of the reduction is continuous and the arrangement has a lateral dimension at the distal end in the region of the photoconductive gap below 20 microns. Furthermore, the invention relates to a near field measurement setup. The invention also relates to a use of the near field measuring tip and / or the near field measuring structure.
