A UNIQUE KNOW-HOW

Close-up of a mirror

Top-flight performance for the most demanding applications

Thanks to its multidisciplinary expertise (mechanical, optical, thermal, etc.), Safran Reosc conducts advanced thermomechanical research, enabling a realistic simulation performance under operational conditions and adjustment of the design to specific needs. Safran Reosc proposes custom-tailored optical coating solutions, addressing all performance aspects beyond spectral response. Safran Reosc offers a broad product range : antireflecting, dichroic, polarizing, narrow-band filtering, absorbent, mirror...

The main challenge when dealing with thin-film optics is to guarantee high performance and reliability even under the harshest environmental conditions, including humidity, temperature, radiation, resistance to laser flux, etc. Reosc’s technologies meet these requirements, and are particular well suited to operations in even most demanding environments: space, cryogenics, high-energy lasers, etc.
