    Throughput Test (M. Loupias & L. Adjali)

    The efficiency performance of the Integral Field Unit is a critical parameter. Coatings performance toward its durability is a difficult trade off to choose. In order to diagnose a throughput loss, we are developping a set up composed of modulated sources, and photodiodes. Our goal is to reach a few percent accuracy and a repeatable set-up.
