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. In March 2007 the qualification and verification phase of the Spectrometer Main Optics (SMO), part of the MIRI spectrometer came to an end. In this phase it is shown that the SMO subsystem can provide the necessary performance and withstand the harsh environments of a launch and outer space. In this phase different models of the SMO have been inspected with respect to performance parameters like alignment and image quality and have been exposed to vibration tests and successive cryogenic cool downs. This paper will describe the philosophy behind the verification plan, the chosen test strategy and reports the results of these tests. In addition the paper covers the design of the optical test setup, focusing on the simulation of the optical interfaces of the SMO.
