Abstract
ESA's Euclid cosmology mission relies on the very sensitive and accurately calibrated spectroscopy channel of the Near-Infrared Spectrometer and Photometer (NISP). With three operational grisms in two wavelength intervals, NISP provides diffraction-limited slitless spectroscopy over a field of deg. A blue grism covers the wavelength range --\,nm at a spectral resolution -- for a diameter source with a dispersion of nm px. Two red grisms span to \,nm at -- and a dispersion of nm px. We describe the construction of the grisms as well as the ground testing of the flight model of the NISP instrument where these properties were established.
