Abstract
MIRI ('Mid Infrared Instrument') is the combined imager and integral field spectrometer for the 5-29 micron wavelength range under development for the JWST. The Flight Model development of the Spectrometer Main Optics (SMO) consisted of small design changes to improve optical performance, structural (dynamic) behaviour and integration based on the experience and verification results of the previous Qualification and Verification models. A full test program was performed in order to keep test efforts at the higher MIRI level as small as possible. The flight model underwent full optical as well as mechanical qualification testing. In December 2008 the SMO was shipped, after successful integration and verification, for final integration within the MIRI instrument. This paper will describe the Flight Model improvements (based on the Qualification and Verification Model test results), the problems and issues encountered during integration and verification and the verification test results.
