Spectral bands for UVS instrument

Note that for any given wavelength, seven different spectral resolutions are available, ranging from 500 to 60,000.

Fig 4: With more than ten times the effective area of HST-COS, combined with a microshutter array, the HabEx UVS provides several orders of magnitude improved efficiency for UV spectroscopic studies. This will enable the first multiplexed observations of multiple sightlines to a single galaxy.
