A UNIQUE KNOW-HOW
Optical systems for astronomy
Drawing on its engineering and technical expertise, Safran Reosc continues to push back the boundaries of possibility to meet the many technological challenges raised by some of the most ambitious projects. Founded in 1937 by Henri Chrétien and Charles Fabry, Safran Reosc has gained significant experience in large and aspheric optics with precision polishing and testing as well as in design, fabrication, assembly and test of robotic telescopes and instruments.
As a participant in major international scientific programs, Safran Reosc manufactured the giant 8.2m Very Large Telescope (VLT) and Gemini active primary mirrors polished well below diffraction limit (down to 8.5nm RMS figure for VLT n° 4), the forty-two1.8 m off-axis segments for the Gran Telescopio Canarias telescope and the seven prototype segments for the primary mirror of the European Extremely Large Telescope (E-ELT).
