PACS Grating Drive Mechanism
AMOS has been awarded by ESA to design and manufacture the PACS Grating Drive Mechanism. PACS was embarked on-Board the HERSCHEL.
The Grating Assembly consists of a flat 320x80 mm2 ruled grating, its positioning mechanism and its launch-lock. The grating is actuated by a cryogenic motor with a resolution of a few arcsec and is installed into the PACS focal plane unit.
Conception and design has been realised to meet severe requirement for an on-board experiment working at cryogenic temperatures. The “Grating Assembly” is strongly lightweighted (3,77 Kg) and composed of Stainless Steel as well as Aluminium 6061T6.
ON FOCUS - Diamond TurningAdvanced 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....
