Abstract

MICADO will be the IR imaging camera for the E-ELT. It has been designed to work in conjunction with both SCAO (in the early phase) and LGS-MCAO system MAORY (for which it has been optimized) and delivers diffraction limited quality over about 1 arcmin field of view covering the wavelength range from 0.8 to 2.5 micron. In this paper, we describe the optical configurations and the observing modes, for both the primary and the auxiliary arms, of the current baseline and we show the expected performances and how the optical path can be folded to fit the available limited space in the cryo-chamber.
