Description: | These pictures are taken during the integration of the Verification Model (VM) of the spectrometer main optics (SMO). The SMO is in development at ASTRON for the Mid Infrared Instrument (MIRI) of the James Web Space Telescope (JWST: the successor for the Hubble space telescope). The VM, as the name already suggests, will be used to perform verification testing of the optical design with respect to performance, image quality etc. under working conditions (vacuum, cryogenic temperature: 7K). |
