NIRSPEC is the Near Infrared Spectrometer at the Keck observatory on Manuakea (4200m), Hawaii. It is a cryogenic cross-dispersed echelle spectrograph which features spectroscopy over the 0.96-5.5 micron range at resolutions up to 40,000 (although currently optimized for RP lower than 25,000). The instrument samples this broad spectral range by employing an array of cross-dispersers and filter configurations. Keck
