4MOST Low Resolution Spectrographs Characterization in Chile
Florence Laurent, Didier Boudon, Eric Daguise +14
4MOST, the 4m Multi Object Spectroscopic Telescope, is the optical, fibre-fed, MOS facility for the VISTA telescope at ESO's Paranal Observatory in Chile. Its main science drivers…
Motorized Mount for the 3-DoF Folding Mirror 2 of the VLT's BlueMUSE Instrument
Gloria Mellinand, Diane Chapuis, Malak Galal +10
BlueMUSE is a blue-optimized, medium spectral resolution, panoramic integral field spectrograph under development for the Very Large Telescope (VLT). The project is now fully enter…

The Blue Multi Unit Spectroscopic Explorer (BlueMUSE) on the VLT: characterization of two VPHG prototypes based on dichromated gelatin and photopolymer recording materials
Alexandre Jeanneau, Andrea Bianco, Andrew Clawson +8
Volume-phase holographic gratings (VPHGs) are widely used in astronomical spectrographs due to their adaptability and high diffraction efficiency. Most VPHGs in operation use dichr…
