THE 182 CM TELESCOPE: INSTRUMENTATION

ECHELLE

The Reosc Echelle Spectrograph provides high dispersion spectra (from 5 Å/mm in the far blue to 10 Å/mm at 6000 Å), with cross-dispersion provided by a grating. The spectrograph can also be used in normal dispersion mode by replacing the echelle grating with a flat mirror and interchanging the slit and comparison lamp slots. The use of the latter configuration is not however encouraged.
