We measured the modulation transfer function for microjetted microlenses with diameters ranging between 109 and 400 µm and with focal lengths ranging between 135 and 540 µm. We found that single-drop 109-µm-diameter microlenses perform close to their theoretical cutoff frequency. However, the larger lenses made with multiple droplets have a cutoff frequency that is 35% of the theoretical value. We interpret this as an illustration of the rapid increase in spherical aberration as the diameter of a lens increases.
