  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 1024x1024 format HgCdTe HAWAII array detector, and
is capable of either wide-field imaging of 1.8'x1.8' field-of-view or
low-resolution spectroscopy from 0.9 to 2.4 um. The limiting magnitudes
measured during test observations were found to be J=23.5mag and K'=22.4mag
(imaging, 1" aperture, S/N=5, 1 hr exposure).
