MICADO, the ELT first-light imager

International audienceThe MICADO instrument is the first light imager of the European ELT. It will work in the near-infrared (0.8-2.4 μm), over a large field (up to 50") and high sensitivity (similar to JWST). MICADO will benefit from two modes of adaptive optics correction: a MCAO correction, uniform on the field of MICADO and developed by the MAORY consortium, and a classic correction of the SCAO type, with high performance in the direction of the star guide and developed under the responsibility of the MICADO consortium. In a phased approach of the integration of adaptive optics to the ELT, MICADO will first be operational in SCAO mode. Offering four observing modes (imaging mode, astrometry, long-slit spectroscopy with R∼20000 and high contrast imaging), MICADO aims to scan a wide range of scientific objectives: small bodies and planets of the solar system, exoplanets and exo-disks, stellar populations in distant galaxies, black holes and the center of our galaxy, evolution and dynamics of galaxies

MICADO:first light imager for the E-ELT

MICADO will equip the E-ELT with a first light capability for diffraction limited imaging at near-infrared wavelengths. The instrument's observing modes focus on various flavours of imaging, including astrometric, high contrast, and time resolved. There is also a single object spectroscopic mode optimised for wavelength coverage at moderately high resolution. This contribution provides an overview of the key functionality of the instrument, outlining the scientific rationale for its observing modes. The interface between MICADO and the adaptive optics system MAORY that feeds it is summarised. The design of the instrument is discussed, focusing on the optics and mechanisms inside the cryostat, together with a brief overview of the other key sub-systems
