Paper describing the IRS instrument on Spitzer. Infrared Spectrograph (IRS) Spectrometer The InfraRed Spectrograph (IRS) was an instrument onboard the Spitzer Space Telescope. It could obtain low-resolution, long slit spectra (R~60-130) from 5.2-38.0 microns and high- resolution spectra (R~600) in Echelle mode from 9.9-37.2 microns. The spectrograph consisted of four modules, each of which was built around a 128x128 pixel array.
