Opto-pyrotechnicsSolutions
SEDI-ATI offers a range of opto-pyrotechnics solutions for space applications

The products are perfectly integrated into all the critical stages of a space mission, guaranteeing optimum performance and rock-solid reliability.
Whether it is verifying the integrity of launchers, separating stages, detaching the fairing, or releasing satellites, these innovative products guarantee maximum precision and safety.
SEDI-ATI can meet the most demanding requirements of the space sector, thanks to its perfect command of advanced optical technologies and its ability to design customized solutions.
The ruggedized multimode multiplexer accepts 105/125 µm core fibers with a numerical aperture of 0.22. The inner dichroic filter is customizable. And the product is compatible with any type of connector or optical contact. It is resistant to high-power pulses (30 W 12 ms).
The fiber-optic harness, single or multi-channel, can be ended with an ELIO contact (or other) and by a MIL-DTL-38999 Series III connector. Robust thanks to its stainless steel protection, it withstands a full temperature range of -80 °C to +120 °C.
The detonator’s optical connector is customizable, featuring a tailor-made dichroic filter deposited at the end interface. Whether in a light or reinforced version, it remains hermetically sealed after detonation. The mechanical parts and seals are defined according to the customer’s specifications.
