Ultracold atomic gases are ideal systems to study many-body quantum physics. The development of new probes offers the possibility to extract more information from these systems. We have developed an apparatus that allows local probing of a degenerate Fermi gas with a resolution of 700 nm. We prepare an optically trapped gas of degenerate ⁶Li atoms in a glass cell sandwiched between two microscope objectives. This setup allows us not only to shape potentials on the scale set by the resolution of the microscopes, but also to probe the state of the atomic ensemble in-situ with high resolution. In this talk we will present results obtained by studying atom number fluctuations of the degenerate atomic cloud.
