Comprehensive, high-performance systems for guaranteed optical quality

tuiles_systemes-doptiques-actives.jpg

Safran Reosc, thanks to its unique expertise, is able to offer very high performance active optics systems. These include a thin, lightweight mirror and support structure equipped with precisely calibrated actuators. Proximity electronics connect the components of the setup and if necessary, an image quality sensor evaluates the quality of the data produced at the telescope's focal point. Safran Reosc's unique expertise in precision optics, large mechanical assemblies, and pointing and coupling devices results in guaranteed system performance.

This technical expertise led to Safran creating the active optics system of the Very Large Telescope (VLT), whose 8-meter M1 mirror is controlled by 150 actuators.
As a longstanding partner of the European Southern Observatory (ESO) organization, Safran Reosc, has been selected to supply the key optics of the Extremely Large Telescope, the world most advanced optical telescope of all time.
