James Webb Space Telescope MIRI Spectroscopy Animation: The beam originating from the telescope is then displayed in deep blue going into the instrument through the pick-off mirror situated at the top of the instrument and imitating a periscope.
Then, a series of mirrors reroute the light towards the bottom of the instruments where a set of 4 spectroscopic modules lie. Once there, the beam is divided by optical aspects called dichroics in 4 beams representing various parts of the mid-infrared area. Each beam enters its own important field system; these elements split and reformat the light from the entire field of vision, prepared to be distributed into spectra. This needs the light to be folded, bounced, and divided lot of times, making this most likely among Webb’s most complicated light courses.
To surface this fantastic trip, the light of each beam is distributed by gratings, producing spectra that then predicts on 2 MIRI detectors (2 beams per detector). An fantastic task of engineering! Credit: ESA/ATG medialab
