Within the framework of a MATRA MARCONI SPACE FRANC contract for the European Space Agency, MATRA DEFENSE - DOD/UAO have developed, produced and tested 9 laser diode collimators, 52 optical components (anamorphoser, mirrors, dichroic splitters, redundancy module) and 9 interferential filters. All these space equipments must be integrated into the optical head of the SILEX (Semi-conductor Laser Intersatellite Link Experiment) bench. The SILEX experiment consists in transferring data from a low altitude satellite (SPOT 4) to a satellite in geostationary orbit (ARTEMIS) via beam generated by a laser diode (60 mW Cw). Very low emitted flux and long distance between the two satellites gives rise to the following technical difficulties: high angular (1 (mu) rad) and transverse stability requirements, requirement for high transmission and high rejection narrow band filters, in order to differentiate the transmit and receive channels, necessity of a very good optical wavefront, wavelength range 815-825 nm, 843-853 nm.
