A multi-instrument focal station for a 2m-class robotic telescope

Abstract

The design of a multi-instrument Nasmyth port for a 2m class telescope, located near Munich, Germany is presented in this paper. A three channel optical and infrared camera will be located at this Nasmyth focus together with an IFU spectrograph, a high resolution Echelle spectrograph, and a Shack-Hartmann sensor for instrument alignment. Fast switching between the instruments and compact design in a small dome are boundary conditions of the project. Precise guiding and acquisition is made possible for all instruments. Calibration sources are fed to the fiber coupled instruments using a built in telescope simulator.
