ELT MICADO Instrument Passes Preliminary Design Review

21 janvier 2020

MICADO, the first dedicated imaging system for ESO’s Extremely Large Telescope (ELT), has reached an important milestone in its design review. The MICADO consortium, together with a group of external experts from around the world, met at ESO’s Garching headquarters for a week of intense examination of the instrument’s optics, mechanics, software, electronics, and budget plan to identify any areas which needed further design work. After the meeting, the MICADO team addressed all of the major concerns raised during the review and the instrument has now formally passed its preliminary design review. A more detailed design phase is now underway, leading towards the final design review and construction of the instrument’s many components.

Equipped for both imaging and spectrographic observations, MICADO — the Multi-Adaptive Optics Imaging Camera for Deep Observations — will focus on near-infrared imaging and spectroscopy with unprecedented combination of sensitivity and accuracy. To compensate for the blurring effect of the atmosphere MICADO will use two different kinds of adaptive optics systems. One will use the telescope’s deformable M4 mirror to provide sharp images over a narrow field of view; the other uses the full capabilities of the MAORY adaptive optics module to provide a wider field of view.

MICADO will have the flexibility to observe many types of objects and its spectroscopic capabilities will add significantly to our understanding of the composition of these objects. The instrument promises to explore some of the most compelling questions in astronomy, including how exoplanets form, how black holes at the centres of galaxies affect their hosts, and how the Universe has evolved over time.
