Description
We present the design and development of the Liverpool InfraRed Imaging Camera (LIRIC) deployed on the 2.0m Liverpool Telescope on the Canary Island of La Palma. LIRIC employs a science grade sCMOS InGaAs detector with a usable imaging area of 607 x 510 pixels, providing a 3.0 x 2.5 arcmin field-of-view. The instrument includes an intergral Starlink Express filter wheel enabling the selection of either a J (1.1-1.4 µm) or H (1.5-1.7µm) filter plus a gold mirror for darks. The compact and lightweight design of the camera assembly allows for rapid repostioning to 17 fixed offset positions within the focal plane using a simple cam mechanism. This provide an alternative to telescope offsetting or using tip-tilt mirror for generating images for sky subtraction.
