Scientific paper

IRIS2 is a near-infrared imager and spectrograph based on a HAWAII1 HgCdTe detector. It provides wide-field (7.7"×7.7") imaging capabilities at 0.4486"/pixel sampling, long-slit spectroscopy at R~2400 in each of the J, H and K passbands, and the ability to do multi-object spectroscopy in up to three masks. These multi-slit masks are laser cut, and have been manufactured for both traditional multiple slit work (~20-40 objects in a 3"×7.4" field-of-view), multiple slit work in narrow-band filters (~100 objects in a 5"×7.4" field-of-view), and micro-hole spectroscopy in narrow-band filters allowing the observation of ?200 objects in a 5"×7.4" field.
