Mersen's key technological contribution to Euclid Mission

Euclid’s first images revealed thanks to Mersen technology

Paris, December 4, 2023 – Mersen (Euronext FR0000039620 – MRN), a global expert in electrical power and advanced materials, has made a key technological contribution to the European Space Agency’s (ESA) Euclid mission, which has just delivered its first images after a successful launch in July.

Mersen Boostec joined the project in 2013, supplying mirrors and structural parts for the large silicon carbide (SiC) telescope to Airbus Defence and Space, the main developer of the payload module. Other major Euclid components, such as the structure of the Laboratoire d’Astrophysique de Marseille’s NISP^[1] instrument, were made by Mersen Boostec using SiC.

A lightweight, robust ceramic that is extremely stable over time, SiC is highly sought after in telescopes for its unparalleled thermomechanical properties, making it possible to capture very high-resolution images with exceptional precision.

Thanks to these unique properties, Mersen is also able to offer silicon carbide products for a wide range of other markets, including as the semiconductor industry, optical and scientific instrumentation, and pharmaceuticals.

Luc Themelin, Mersen’s Chief Executive Officer, said: “We’re very proud to see our technology contribute to gathering extremely precise images that will help us better understand our universe. I would like to thank Airbus Defence and Space for letting us be part of this technical and scientific mission to unlock the secrets of how the universe is expanding.”
