Resonant absorption imaging is a common technique for detecting the two-dimensional column density of ultracold atom systems. In many cases, the systems thickness along the imaging direction greatly exceeds the imaging systems depth of field, making the identification of the optimally focused configuration difficult. Here we describe a systematic technique for bringing Bose-Einstein condensates (BEC) and other cold-atom systems into an optimal focus even when the ratio of the thickness to the depth of field is large: a factor of 8 in this demonstration with a BEC.
