Paper Abstract

We present the design of the High Resolution Spectrograph (SARG, 25,000 <EQ R <EQ 200,000) for the Italian Galileo National Telescope (TNG). SARG will be a fiber-fed, white-pupil echelle spectrograph, with prismatic cross disperser and two cameras, placed in a temperature controlled room in the telescope pillar. Additionally provision has been made for a cryogenic IR arm extending the spectral coverage up to 1.7 micrometers . Novel features include a new design of the fiber spectrograph interface and an asymmetric white-pupil collimator.
