Paper Abstract

The preliminary design for the f/5 Nasmyth tertiary mirror opto-mechanical configuration for the 6.5m Telescopio San Pedro Mártir (TSPM), to be installed at the Observatorio Astronómico Nacional (OAN) in the Sierra San Pedro Mártir in Baja California is presented. The proposed system consists of support and alignment of the honeycomb mirror within the cell, the correction of the optical surface deformation, both tasks by means of an active push-pull pneumatic system and the correction of the displacements and rotations transferred by the Tube support structure to the configuration by means of electro-mechanical actuators. This optical configuration and four folded Cassegrain stations will be fully defined after first light of the f/5 Cassegrain configuration, so the requirements and considerations of these positions also need to be taken into account.
