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 λ/Δλ≈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.
