Direct-drive fusion implosion experiments using the 60-beam OMEGA Laser System require ~1% rms uniformity on target. To fully characterize on-target uniformity, a full-beam in-tank diagnostic that measures the on-shot, full-energy focal spot of 28 of the 60 beams inside the target chamber was deployed in 2018. While this diagnostic demonstrated the absence of gross nonuniformities, questions about lower-level variations and their effects on overall uniformity remained. We will present improvements in dynamic range, a new wavefront measurement capability, a summary of the 28 beams characterized to date, and a discussion of observed differences between beams under varying shot conditions.
