No known issues.


ODI shutter closed when humidity ≥ 80% [07/06/2022]
The ODI dewar window is prone to condensation under high humidity conditions. Since condensation will leave a residue, and every condensation event will fog up some parts of the dewar window long-term. This diminishes the throughput significantly (up to a factor of 2), and in a patchy, non-calibratable way. It is therefore imperative to avoid any condensation event.
