Optomechanical design of a broadband cryogenic optical system for ground testing of the Ariel payload

ESA’s Ariel space telescope is due to launch in 2029 and aims to measure broadband (0.5 – 7.8 µm) spectra from ∼1000 known transiting exoplanets. For optimum stability the payload uses an all aluminium telescope with an extremely narrow (30 ′′) field of view. Prior to integration with the spacecraft, the Ariel payload...
