Abstract

The alignment of an instrument plays a fundamental role in its final performances. In the astronomical field, this operation has always been performed using external optical feedback in an iterative process. The aim of the paper is to study a different integration procedure devised to reduce the number of iterations for a big instrument composed by several optical elements in the 1-meter class. The proposed procedure consists to in the geometrical measurement of the as-built optomechanical elements followed by the integration in the nominal position. The case study for this work is MAORY @ ELT and the accuracy evaluation, since the instrument dimensions require a large metrological system, is performed considering a Laser Tracker (LT). The final accuracy budget will take into account all the source of errors that are presents during the different phase of the instrument integration.
