LIRIC under development in lab (covers removed). ©2023 A.Piascik
The Liverpool Infra-Red Imaging Camera is an instrument development project co-funded by STFC and LJMU. It was designed and built by the ARI and will be available from 2024 Q1, replacing the now-decommissioned IO:I camera. It offers rapid X and Y axis fixed-distance offsetting (nodding) for sky background subtraction.
Under development at ARI; scheduled for deployment 2024 Q1.
