BlueMUSE is a blue-optimised, medium spectral resolution, panoramic integral field spectrograph based on the MUSE concept and proposed for the Very Large Telescope.
With an optimised transmission down to 350 nm, a larger FoV (1.4 × 1.4 arcmin2) and a higher spectral resolution (λ/Δλ ~ 4000) compared to MUSE, BlueMUSE will open up a new range of galactic and extragalactic science cases allowed by its specific capabilities in the 350-580nm range, beyond those possible with MUSE.
In this paper, we present the optomechanical architecture and design of BlueMUSE at pre-phase A level, with a particular attention to some original aspects such as the use of curved detectors.
