2 Description of the Spectrograph

In this section a description of each element of the spectrograph is given, progressing through the light path. The optical diagrams in figure 1 may be consulted for the arrangement of these elements. The prospective user need not be intimidated by the apparent complexity of the echelle spectrograph, since the actual operation of the instrument is straightforward, and the instrument assistant and telescope operator will handle most of the setup and computer interaction.
