General

EMMI Optical Layout

EMMI is a multipurpose instrument allowing observations in the visible wavelengths. EMMI supports the following observation modes:

Wide-field imaging,
Low-resolution multi-object or long-slit grism spectroscopy,
Medium-resolution long-slit grating spectroscopy
Echelle spectroscopy.
