Happy Birthday SPHERE!

      Comments Off on Happy Birthday SPHERE!

One year after the first light, we are still working on the instrument to enhance its performance. This week is dedicated to the in-lab integration of the SPHERE active optics module, namely the Active-TM3. Below you see the brainstorming results, the CAD models and the mirror before integration. The “Tiger team” is composed of Sabri Lemared, who designed the active warping harness, Zalpha Challita, who performs the system gluing, and Kjetil Dohlen, the SPHERE system engineer, while I am in charge of the overall coordination and of the optical testing and charaterisation.This work¬† is the concretisation of the research done in the frame of the young researcher program ANR-OASIX, which results in the realisation of this on-sky module.
