Paper Abstract

Sofradir is one of a leading company of the world for the development and production of infrared detectors. Main applications of these detectors are tactical and commercial applications but also space applications. In particular, Sofradir started to work in the field of space applications and especially in the earth observation domain in the beginning of the 1990th. Thanks to the work done with the support of the French Ministry of Defense and the European Space Agency, Sofradir has acquired a large know-how and became a major supplier for space industry. Nowadays, Sofradir technologies offer possibilities to develop a large panel of high reliable detectors like long linear arrays or two dimensional arrays covering bandwidth from visible to 15 μm based on qualified Mercury Cadmium Telluride (MCT) technology. As a matter of fact, Sofradir is involved in several projects for future space missions (SPIRALE, Sentinel-2 for GMES, MTG, SGLI...) covering a spectral range from visible to long wavelength infrared. In this paper, we present a review of Sofradir technology for the development and manufacturing of infrared detectors for space applications. A particular emphasis is made on the different programs currently run with a presentation of the associated results in terms of performances and qualifications for space use.
