ELT : MICADO enters the manufacturing phase

17 mai 2023

MICADO, the first light camera for ESO’s Extremely Large Telescope (ELT), is nearing completion of its design phase. The partners of the MICADO consortium, including the Observatoire de Paris - PSL, have started the fabrication of the different subsystems of the instrument.

After a lengthy design phase, the MICADO consortium partners recently shared photos of some of the subsystems currently being manufactured.

Discover Micado in video

On the occasion of this important project milestone, ESO (in collaboration with the MICADO consortium) has produced the first episode of an explanatory video series, presented live on the ESO YouTube channel on Friday, May 12, 2023.

MICADO will equip the Extremely Large Telescope (ELT) with a first imaging capability to provide high-resolution images of the Universe at near-infrared wavelengths.

It will be the ideal instrument to identify exoplanets, reveal the detailed structure of distant galaxies, or study individual stars in nearby galaxies. MICADO will also be a unique and powerful tool for exploring environments where gravitational forces and the effects of general relativity are extremely strong, such as those exerted near the supermassive black hole at the center of our Milky Way galaxy.

The high technology implemented in the instrument will allow it to go far beyond the capabilities of the best observatories we have today, including those of the Hubble Space Telescope. Its sensitivity will be comparable to that of the James Webb Space Telescope, but with six times the resolution.

French contributions to MICADO

France is a major partner of the MICADO consortium with the responsibility of the adaptive optics system of first light of the instrument and its high contrast imaging mode. Under the direction of LESIA at Paris Observatory - PSL, these developments also involve several French laboratories and national structures :

  • Laboratoire d’études spatiales et d’instrumentation en astrophysique de l’Observatoire de Paris - PSL (LESIA – Observatoire de Paris - PSL)
  • Laboratoire Galaxies, Étoiles, Physique, Instrumentation de l’Observatoire de Paris - PSL (GEPI – Observatoire de Paris-PSL / CNRS / Sorbonne Université / Université Paris Cité)
  • Institut Univers, Temps-Fréquence, Interfaces, Nanostructures, Atmosphère et Environnement, Molécules (UTINAM – OSU THETA)
  • La division technique de l’INSU (DT INSU)
  • Laboratoire Charles Fabry (LCF - CNRS / Institut d’Optique Graduate School / Université Paris-Saclay, Institut : INSIS)
  • Laboratoire des Matériaux Avancés – IP2I (LMA - CNRS / Université Claude Bernard Lyon 1, Institut : IN2P3)

The ELT and MICADO are expected to begin operating by the end of this decade.
