Abstract
HORIBA Scientific develops since several decades, through missions in collaboration with prestigious space agencies, state of the art of scientific diffraction gratings dedicated to space applications for embedded telescopes or imaging spectrometers. The presentation will introduce some of our latest developments conducted on the past years related to earth observation. These realizations were done for SENTINEL 5 (ESA – European Space Agency), MICROCARB (CNES - Centre National d’Etudes Spatiales) and GeoCARB (NASA - National Aeronautics and Space Administration) instruments or missions. Different types of gratings were developed and manufactured: gratings on a prism (grisms) and high working order replica gratings on plane substrat (Echelles). We will introduce these projects and explain the challenges represented by each type of grating and performances obtained for each mission.
