Abstract

The ESA/EUCLID satellite is equipped with two instruments that are simultaneously observing patches of < 0:5 square degree on the sky. The VIS visual light high spacial resolution imager and the NISP near infrared spectrometer and photometer are separated by a di-chroic beam splitter. The NISP Near Infrared Spectrometer and Photometer reduces the initial f/# 20 beam of the Korsch type telescope to an f/# 10 beam filling 16 Hawaii 2RG detectors on the NISP instrument focal plane by means of a four lens optical system. With this paper we present tests on the radiation damage measured between 500 and 2000nm to six 25mm thick probes of optical materials potentially used in the NISP optics for the environmental conditions expected for a six years mission in the outer Lagrange point L2.
