Paper Abstract

We start off with the 1 meter experiment. The principles of active optics and the results of the 1 meter experiment are described in detail in three papers 1, 2, 3. The support geometry is identical to the one of the NTT primary mirror. The 78 actuators, 75 of them astatic levers with movable counterweights, are located on four rings with three fixed points on the third ring. The mirror is a spherical mirror of 1 meter diameter and a thickness of 19 mm.
