Abstract
We present the science, design and performances of DIORAMAS, an imager and multi-slit spectrograph for the European Extremely Large Telescope. It covers a wide 6.8x6.8 arcmin2 field, a large wavelength range 0.37 to 1.6 microns. The exceptional performances of this concept will enable extremely deep images to magnitudes AB~30 and high multiplex spectroscopy with up to ~500 slits observed simultaneously at spectral resolutions from R~300 to more than 120 slits at R~3000. The technical design is robust with only proven technology, and DIORAMAS could be developed on a timescale compatible with the EELT first light.
