Abstract

The OPTIMOS-EVE concept provides optical to near-infrared (370-1700 nm) spectroscopy, with three spectral resolution (5000, 15000 and 30000), with high simultaneous multiplex (at least 200). The optical fibre links are distributed in five kinds of bundles: several hundreds of mono-object systems with three types of bundles, fibre size being used to adapt slit with, and thus spectral resolution, 30 deployable medium IFUs (about 2"x3") and one large IFU (about 6"x12"). This paper gives an overview of the design of each mode and describes the specific developments required to optimise the performances of the fibre system.
