We present the progress towards constructing a dipolar quantum gas microscope. This new apparatus combines the long-range interactions found in dipolar quantum gases with the single-site resolution of a quantum gas microscope, allowing for detailed studies of quantum phases in strongly correlated systems. Fermionic atoms trapped in optical lattices can model the behaviour of electrons in complex solid materials. By implementing a quantum gas microscope, microscopic details such as site occupation and site correlations will be observable, providing new insights into elusive quantum phases. We plan to do this using dysprosium atoms trapped in an ultraviolet optical lattice with a lattice spacing of about 180 nm. Combined with the long-range dipole interaction, the short lattice spacing will significantly increase the nearest-neighbour interaction strength to be on the order of 200 Hz (10 nK). This will allow us to study the regime of strongly interacting dipolar Bose- and Fermi-Hubbard physics where even next-nearest-neighbour interactions could be visible.
