Safran Reosc has been founded in 1937 by a group of scientists from the Paris Institute of Optics, including Henri Chretien, inventor of the so-called Ritchey-Chretien telescope, and Charles Fabry, inventor of the Fabry-Perot interferometer.
After initial activities dedicated to IR and defense applications Safran Reosc rapidly evolved as the French leader in large optical instrumentation for astronomy. When spaced business emerged with the creation of the Centre National d'Etudes Spatiales (CNES), Reosc also developed a leadership in space optics.
In parallel, the former Matra Optique Division developed high skill in high performance dioptric optics and high performance optical coatings, especially for high energy laser for the Centre d'Etude Atomique (CEA).
Safran Reosc became subsidiary of Sfim in 1978, merged with Matra Optique in 1996 and was absorbed by Sagem in 1998. In 2013 Safran Reosc was set back as an SME, 100% subsidiary of Sagem, now Safran Electronics & Defense.
Some key achievements
Safran Reosc is a champion in high performance optics and its history is paved with some famous milestones and world records as follows:

Adress: Safran Reosc - Avenue de la Tour Maury - 91280 Saint Pierre du Perray - France
Our main building includes all design, manufacturing, AIT means and administrative offices with:
- A total floor area of more than 6000 m² with a two-level office building
- 600 m² ISO 6 clean room for the thin film lab
- 400 m² ISO 6 + 200 m² ISO 5 clean room for AIT
Our giant optics polishing shop, has been set-up in a separate building for the contract for the Very Large Telescope (VLT) 8-m mirrors polishing is unique over the world and act like a long-distance seen lighthouse with its 30-m high tower constituting the vertical optical test bench for these giant optics. After VLT, the shop was adapted to the serial production of the Gran Telescopio Canarias (GTC) 42 1.8-m hexagonal segments. In 2016 the shop is again transformed for the polishing and testing of the E-ELT M2 4-m convex mirror for which we have been contracted by the European Southern Observatory (ESO).

Safran Reosc's Quality Policy is aimed at involving the company in a process of continual improvement, crucial for reaching its goals of excellence for products and services and, thus, providing customer satisfaction.
This policy focuses on five areas of priority, defined in consistency with the Safran Group values, applied in all the different company sectors:
- Customer satisfaction
- Company quality culture
- Development quality
- Product / process robustness
- Supplier quality and supply chain
Company quality and deployment of the quality policy are based on a Quality Management System and internal processes.
Quality Management System
The Quality Management System is based on an organization, in charge of developing the company according to its strategic goals, and on processes aimed at developing a continual improvement approach. The QMS is also formalized in a structural set of reference documents making it possible to conduct projects in compliance with standards, as well as capitalize on company know-how and guide its improvement-oriented approach. Safran Reosc is organized into line management and staff management. Quality management, also structured in consistency with the company's operational organization, is in charge of guaranteeing the quality of products delivered to customers, the respect and improvement of processes, and offering shared methods and tools for quality.
The top goal, developed in the quality improvement plans drawn up per division and per product line, is to deliver quality products within the scheduled time period. These improvement plans incorporate how to deal with non-quality faster, assess whether processes and guidelines are respected, take into account experience feedback, as well as how to improve the reliability of industrial processes, reinforce the quality of industrializations and optimize manufacturing cycles.
The development of methods and quality training for teams is a key success factor in Safran Reosc core activities, involving a high degree of highly skilled labor. The implementation of proven methods of Corrective and Preventive Actions (PDCA, 8D, FMECA Product/Process, HAT/HASS, Lean-Sigma, etc.) make it possible to foresee problems and, if need be, identify them and solve them quickly.
Safran Reosc uses quality guidelines set out in manuals, process description documents, procedures and instructions, based on international standards (ISO9001, EN9100 and EN9110). The organization of these various components is presented in the company Quality Manual, and for Civil Aviation regulations in the Production Organization Manual (POM) and the Maintenance Organization Exposition (MOE).
Certificates and accreditations
To meet customer expectations concerning Safran Reosc's high-technology products and services, in terms of Quality, Costs and Deadlines, Reosc has built and deployed a Quality Management System based on aeronautical standards EN9100 and EN9110, resulting from the ISO 9001 standard, providing additional guarantees of compliance.
Safran Reosc holds certificate testifying to the compliance of its Quality Management System with international Best Practices, according to ISO9001:2008 (according to ISO - International Standardization Organization).
