UT Fork

UT Fork


AMOS has studied the fork of the 8 m unit telescope of Paranal for the European Southern Observatory.

The aims of the study were:

  • to provide a rigid interface (Eigen frequency as high as possible) between the base and the tube;
  • to reduce the level of the altitude axis;
  • to bring the total weight of the telescope unit to a minimum.

The AMOS study arrived at the following values:

  • mass of the fork: 87 t (150 t less than a classical solution)
  • first Eigen frequency at 9 Hz
  • level of the altitude axis: 6.7 m above the base level

These characteristics were obtained with a double concentric circular azimuth track.

Overall fork dimensions:

  • Length: 24 m
  • Width: 8.1 m
  • Height (bearings included): 8.25 m


 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....
