NIRSpec, or the Near Infrared Spectrograph, is a scientific instrument aboard the James Webb Space Telescope (JWST). It is designed to perform spectroscopy in the near-infrared range (0.6 to 5 microns), allowing scientists to study the composition, temperature, density, and motion of various astronomical objects, including stars, galaxies, and exoplanets.

NIRSpec provides multiple spectroscopic modes within –. Its time-series modes can measure exoplanet transmission spectra and exoplanet secondary eclipses; individual settings have narrower coverage. See NASA's instrument overview.
