spectrograph
NIRSpec is the Near-Infrared Spectrograph aboard the James Webb Space Telescope, supporting fixed-slit, integral-field, time-series and multi-object spectroscopy.
NIRSpec is the Near-Infrared Spectrograph aboard the James Webb Space Telescope. It is designed to obtain spectra at near-infrared wavelengths, operating across approximately 0.6 to 5.3 micrometres. Its observing modes include fixed-slit, integral-field, time-series and multi-object spectroscopy, allowing spectra to be gathered in different observational configurations. A microshutter array permits the simultaneous collection of spectra for more than 100 targets. ESA provided the array, with NASA subsystems. NIRSpec is an instrument rather than a separate telescope or mission; its stated capabilities describe spectroscopic observing modes and wavelength coverage, not results for any particular target.
