Abstract

Wide-field infrared cameras, operating on the new generation of large telescopes, offer unprecedented gains in the detection of faint sources and in observing efficiency for both direct imaging and spectroscopy. PISCES, a near-IR (1-2.5 micron) wide-field camera designed for the f/9 secondaries of the Steward 2.3m and 6.5m MMT, is one such instrument that has been operational for over one year. Equipped with a 1024×1024 HAWAII HgCdTe array, PISCES offers an 8.5 arcminute field at the 2.3m and a 3.1 arcminute field at the MMT. Here we present our design to upgrade PISCES with a low resolution (R=200-500) grism for single and multi-object spectroscopy. The design allows J, H, and K-band spectroscopy in orders 5, 4 and 3, respectively. The combination of 6.5m aperture and multi-object capability will make PISCES a powerful tool for extending our knowledge of the low-mass regime of the initial mass function as well as star-formation in 0.5 < z < 1 galaxy clusters. We discuss design and fabrication issues and simulate the performance of the grism systems.
