On demand | Presented live 20 June 2024 
Abstract
Photonic Lanterns (PLs) play a crucial role in astrophotonic technologies, converting multi-mode inputs to single-mode outputs with low losses. Despite technical advancements, the reproducibility of PLs remains unexplored. We present a study characterizing multiple PLs to address the challenges of mass production. Initial results indicate high taper rate consistency, vital for PL stability and their integration into astrophotonic instruments. Beyond taper measurements, our comprehensive evaluation includes throughput, near-field, and chromatic analyses, ensuring mass produced PLs meet stringent telescope requirements.
