Freeform optics design and manufacturing for MicroCarb

In dec 2015, during COP21, France has initiated the development of the MicroCarb satellite dedicated to better understand the carbon cycle within our atmosphere and to predict its evolution. CNES selected Airbus Defense and Space for the development of the instrument and Safran Reosc has been selected for the optical polishing of the key optical components of this innovative compact spectrometer, the first in EU of its class entirely based on precision freeform optics. The benefits of freeform optics will be highlighted before introducing to the MicroCarb satellite and instrument optical design. Our joint design efforts with Airbus Defense and Space towards ‘feasible’ optics will be presented with the latest technology development at Safran Reosc on freeform optics polishing technology.
