ALSYMEX, ADR and EPSYL work in the field of astrophysics.
ALSYMEX
ALSYMEX offers the scientific community in the field of astrophysics mechanical and optomechanical assemblies integrated into ground or on-board telescopes.
ALSYMEX has therefore been heavily involved in the construction of a prototype of a small size telescope (SST) for the future CTA European program for exploring the universe in gamma rays: production of metallic reflectors and support structures.
ADR
Electro-optical subsystems. ADR supplies integrated bearings for the EUCLID space telescope.
EPSYL
Thermal and multi-physics engineering. EPSYL is in particular involved in the JSWT and M1 Solar Orbiter projects of France's CNES and the ESA.
