Abstract:
This paper describes a Cooled Infrared Spectrograph and Camera for OHS (CISCO), mounted on the Nasmyth focus of the Subaru telescope. It is primarily designed as a back-end camera of the OH-Airglow Suppressor (OHS), and is also used as an independent, general-purpose near-infrared camera/spectrograph. CISCO is based on a single $ 1024 \times 1024$ format HgCdTe HAWAII array detector, and is capable of either wide-field imaging of $ {1\rlap {.}{}^{\mathrm {\prime }}8} \times {1\rlap {.}{}^{\mathrm {\prime }}8}$ field-of-view or low-resolution spectroscopy from 0.9 to 2.4 $ {\mu \mathrm {m}}$. The limiting magnitudes measured during test observations were found to be $ J=23.5 \,\mathrm{mag}$ and $ K^{\prime} = 22.4 \,\mathrm{mag}$ (imaging, $ {1{}^{\mathrm {\prime \prime }}}$ aperture, $ \mathrm{S} / \mathrm{N} = 5 $, 1 hr exposure).
