|Description:|| First cryogenic images from fully integrated JWST-MIRI verification model in test facility at Rutherford Appleton Laboratories; system temperature ~43 K, detectors at 6.7 K.|
“The main thing to report […], is that both the imager and spectrometer are looking very good optically. The spectrometer slices are as expected from modelling. The fringes are due to the detector substrate behaving like an etalon which is also predicted from modelling. The wavelength range is confirmed to be 5.7 to 6.7 micron in channel 1B (on the left) and 8.7 to 10.3 micron in channel 2B. The imager PSF at 11.3 micron is also as expected from modelling.”
