PROBA V
Structure and Mirror Manufacturing

Proba V is a Small Observation Satellite initiated by the European Space Agency.
From 2012, it shall provide a global coverage and a continuous stream of data on the status of the Earth vegetation, crops and forest.
The optical surfaces of these Three Mirror Anastigmat instrument are machined at AMOS by Single Point Diamond Turning (SPDT). The resulting surface roughness (4nm RMS) is compliant with the instrument multi-spectral applications, without need of post-polishing.
The highly aspherical surfaces are measured by null test with dedicated Computer Generated Holograms (CGH). A surface accuracy better than 35 nm RMS are achieved on the largest mirrors.
The structure offers interfaces whose severe position accuracy made possible a simple and straightforward assembly and alignment.

 ON FOCUS - Diamond Turning

Advanced Mechanical and Optical Systems (AMOS) manufactures small optical pieces by diamond turning mainly for infrared applications but also, after post polishing, for visible or ultraviolet. Concave or convex mirrors up to 500mm can be machined with extreme asphericities....
