The Mid-Infrared Instrument for the James Webb Space Telescope, II: Design and Build
The Mid-InfraRed Instrument (MIRI) on the James Webb Space Telescope (JWST) provides measurements over the wavelength range 5 to 28.5 ÎŒm. MIRI has, within a single âpackage,â four key scientific functions: photometric imaging, coronagraphy, single-source low-spectral resolving power (R ⌠100) spectroscopy, and medium-resolving power (R ⌠1500 to 3500) integral field spectroscopy. An associated cooler system maintains MIRI at its operating temperature of < 6.7 K. This paper describes the driving principles behind the design of MIRI, the primary design parameters, and their realization in terms of the âas-builtâ instrument. It also describes the test program that led to delivery of the tested and calibrated Flight Model to NASA in 2012, and the confirmation after delivery of the key interface requirements
