Imaging using charged particle optics presents itself as a powerful approach towards pushing the limits of probing ultracold quantum gases. Here, we present a high-resolution ion microscope [1] as a versatile tool to investigate ground-state ensembles, Rydberg excitations, and ionic impurities with exceptional spatial and temporal resolution on a single-atom level. Using ionized ultracold Rubidium atoms, a highly tuneable magnification ranging from 200 to over 1500, a resolution better than 200nm and a depth of field of more than 70µm were demonstrated, which enables the study of bulk quantum gases and phenomena ranging from microscopic few body processes to extended many-body systems. Moreover, a pulsed operation mode of the microscope was illustrated which enables the compensation of electric fields which further aids in the study of highly excited Rydberg atoms and cold ion-atom hybrid systems. Furthermore, the pulsed operation mode facilitates the investigation of dynamical time-dependent studies and three-dimensional imaging, where the latter was demonstrated by utilizing the time-of-flight information of the detected ions.
