Optical instruments

Optical instruments for space exploration require precise and stable geometrics that can withstand drastic changes in temperature. Our expertise in sintered silicon carbide Boostec® SiC is a pioneer technology, enabling us to explore the universe.

space telescope SiC Mersen

Ground-based observatories

Ground-based observatories benefit from the same remarkable properties of Boostec® SiC, in particular for their mirrors or their adaptive optics.

Mersen is taking part in the Extremely Large Telescope (ELT) project run by the European Southern Observatory (ESO), helping to complete the fifth and final mirror for this giant future telescope, which is the most powerful in the world.
