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 four kinds of bundles: several hundreds of mono-object systems with three types of bundles, fibre size being used to adapt spectral resolution and 30 deployable medium IFUs (about 2"x3"). We are optimising the design of deployable IFUs to warrant sky subtraction for the faintest extragalactic sources. This paper gives the design and results of the prototype for the high resolution mode and the preliminary design of a medium IFU developed in collaboration between the GEPI and the LNA.
