Tspm F/5 Nasmyth Configuration

We present the optical design, the error budget, the differential distortion budget and the baffle design of the Telescopio San Pedro Martir f/5 Nasmyth configuration. The TSPM in its Cassegrain configuration will be assembled around a closed design (converted MMT/Magellan telescope) with most of its optical parts already manufactured. To anticipate for future possible upgrades, the project includes the design of an extreme f/5 Nasmyth configuration. Our optical design demonstrates the feasibility of the configuration, closes the interfaces to the telescope, provides a full picture of the expected performance, and identifies the critical points involved in the configuration.
