The company AMOS was launched in 1983, merging the mechanical machining expertise of “Ateliers de la Meuse” with the optical polishing know-how of the Institute of Astrophysics from the University of Liège.

Located at the heart of the “Liege Science Park” in Sart Tilman, Liège, Belgium, AMOS has been designing and building high-precision optical and mechanical custom equipment for more than 30 years. Its flagship achievements are professional telescopes, terrestrial or space optical systems, test equipment for space devices, and high-precision mechanical equipment. It occupies today more than 100 employees highly skilled in advanced technologies and offers services to the space industry and to the professional astronomy sector.


The company has most of its customers in Europe (ESA, ESO, AIRBUS DEFENSE & SPACE, THALES ALENIA SPACE, OHB), in the United States (AURA), in India (ISRO, PRL, ARIES), and has recently expanded its business in countries like China, Turkey or Russia.


AMOS focuses on 3 main areas:

  • Professional astronomy systems: Medium and large telescopes (as turn-key solutions), telescope subsystems and auxiliary systems.
  • Space systems: On-board opto-mechanical systems and mirrors, large thermo-vacuum chambers, collimators, optical test benches, etc.
  • Industrial systems: High-precision mechanical assemblies or vacuum chambers for industry.
