CUBES is a high-efficiency, medium-resolution (R ∼ 20,000) ground-based UV (300–400 nm) spectrograph, to be installed in the Cassegrain focus on ESO’s Very Large Telescope (VLT) UT-2 at Cerro Paranal Chile.

Astralis has joined the Phase A study to provide a concept design for a Fibre Link between the planned CUBES spectrograph and another spectrograph located at VLT.
