Description

To characterize the Near Infrared Spectro-Photometer (NISP) instrument optical capability before the launch in orbit of the Euclid telescope, foreseen in 2023, data analysis of ground-based campaign tests made in laboratory as well as Monte Carlo simulations that mimic the expected NISP performances have been perfomed.
These pre-launch tests have been analyzed to assess the fulfillment of the mission specifications in terms of Point Spread Function (PSF), i.e. EE50(PSF) ≤ 0.3 pixel, and spectral calibration, i.e. σ(λ) < 1 pixel or Δz/z ≤ 0.001, as well as to provide a first comparison between real images from the ground-based campaign tests and simulated images.
We confirm the high optical quality of the NISP instrument, fulfilling the mission specifications in terms of PSF and spectral calibration with a great stability between the different campaign tests. A first comparison between simulations and data obtained from the ground-based campaign tests will be provided.
