SEDI ATI

SEDI-ATI Fibres Optiques is a French company that specializes in designing and manufacturing custom fiber optic-based passive components.

Our products are designed to meet the demands of very challenging environments, such as military, aerospace, industrial, medical, and research markets.

We are certified with ISO 9001 and ISO 13485 certifications, and our solutions are specifically developed to withstand hostile conditions such as vacuum, pressure, radiations, cryogeny, high-temperature...

Our fiber-optic product ranges include:

• fiber-optic hermetic feedthroughs for vacuum and pressure,
• bundles and arrays for spectroscopy applications,
• bundles for high-temperature,
• special patchcords for vacuum / radiations / cryogeny...,
• highly achromatic multimode couplers,
• multimode wavelength division multiplexers,
• miniature lightweight fiber-optic links and connectors,
• deployable fiber-optic spools for unmanned vehicles,
• and fiber optic medical probes for endovenous treatment.

SEDI-ATI is capable of working with any optical fiber provider and supplying various types of optical fibers to manufacture its components. The types of fibers that we work with include singlemode, low wavelength, polarisation maintaining, and multimode gradient index and step index.

Our fields of application range from UV-VIS-IR, spanning from 180 nm to 14 µm.

We work with a variety of materials such as silica/silica (doped, ultra pure…), silica/polymer (HCS hard-clad silica), sapphire, fluoride glass (fluorozirconate, fluoroaluminate, …), chalcogenides glass (CIR), silver halide (PIR), hollow fiber, plastic (standard and scintillant), and coatings such as acrylate, nylon, ETFE, polyimide, metal (aluminium, copper, gold)… Our fiber core types include circular, square, rectangular, and octagonal.

We maintain a permanent stock of more than a hundred references of various optical fibers and have developed a strong expertise enabling us to choose the most appropriate optical fibers to match our customer's applications.
