Abstract

The foundation of the MUSE instrument with its high multiplexing factor of twenty-four spectrographs is formed through its central main structure that accommodates all instrumental subsystems and links them with the telescope. Due to instrument's dimension and complexity, the requirements on structural performance are demanding. How its performance was tested and optimized through reverse engineering is addressed. Intimately mated with this central structure is an optical relay system that splits the single telescopic field into twenty-four subfields. Each of those is individually directed along three dimensions across the structure through a folding and imaging setup of an optical relay system that at the end feeds one of the twenty-four spectrographs. This opto-mechanical relay system was tested when mounted onto the main structure. The results obtained so far are given here.
