Contribution
This paper introduces the design, science goals, and expected performance of METIS, a new mid-infrared instrument for the ELT with advanced adaptive optics and spectroscopy capabilities.
Findings
Enables high contrast imaging at 3-13 microns
Provides integral field spectroscopy with R~100,000
Offers diffraction-limited performance with adaptive optics
Abstract
The Mid-infrared ELT Imager and Spectrograph (METIS) will provide the Extremely Large Telescope (ELT) with a unique window to the thermal- and mid-infrared (3 - 13 microns). Its single-conjugate adaptive optics (SCAO) system will enable high contrast imaging and integral field unit (IFU) spectroscopy (R~100,000) at the diffraction limit of the ELT. This article describes the science drivers, conceptual design, observing modes, and expected performance of METIS.
