MMCS
was designed for spectral observations of faint objects at the Cassegrain
focus (F/8) of the telescope ZEISS-2000. It has a modular design which allows quick
transformation from its echelle to prism mode. Thus the spectrometer
has wide range of resolutions from 100 to 15000 and spectral range
3700 - 8000 Å
