WebNotes on ghosts. At present, for spectroscopy using dichroics, there are ghost spectra that have been determined to be second order light dispersed by the red side grating that is returned to the dichroic (and which passes through because the dichroic is basically a long-pass filter) and then makes it onto the blue side detector as zeroth order light (i.e., it … WebThe Mid Infrared Instrument (MIRI) aboard JWST is equipped with one filter wheel and two dichroic-grating wheel mechanisms to reconfigure the instrument between observing …
