BUILDING FACILITIES

AMOS : new building situated in Research Park of the University of Liège, equipped with a clean room, welding facilities, work shops with hydrometry and temperature control, polishing facilities in clean room.

AMOS has an optical workshop for mirror fabrication up to 1.8 m diameter and the necessary metrology equipment for optics qualifacation. A coating chamber for pieces up to 400 mm diameter.

AMOS has received an important government investment to develop a new large optical workshop (for mirror up to 3 m diameter, possibility to increase to 3.5 m).
This workshop includes mainly:

• grinding and polishing machines computer controlled;
• an interferometry test tower (12 m height) with a movable platform equipped with a ZEISS interferometer DIRECT 100 and an holography test bench.
