French company founded in 1951, our mission at SEDI-ATI is to design and build turn-key solutions based on optical fibers to enable you to bring photons in any environment, whatever your constraints are! By extreme environments we mean: • High temperatures ranging from 125°C up to 600°C and even 1000°C • Low temperatures down to -273°C • High pressures up to 1500 bars for geophysics and even 5000 bars for detonics • Hermeticity down to 10-9/10-10 • High voltage dielectric breakdown up to 1KV per cm • Very high level of cumulative nuclear radiations in front of a nuclear reactor • UV solarization resistance down to 200nm • and so on… SEDI-ATI offers a wide range of special products such as: • bidirectional couplers & WDMs for sensors, diagnosis and monitoring applications • hermetic feedthroughs for vacuum and pressure applications • bundles & arrays for spectrometry and sensors • fiber optic spools for remotely operated vehicles • fiber optic pigtails, cables and connectors • fiber optic medical probes Our customers markets include: • Military and Aerospace: satellites, laser ignition, unmanned vehicles… • Energy: nuclear plants, Oil & Gas, electric power distribution, sustainable energies… • Industry: power lasers, transportation, sensor systems, robotics… • Medical: diagnosis and analysis, laser surgery treatment, endovenous laser therapy, photodynamic therapy… • Research: astronomy, particle physics, biology…
