TS4 ARCoIRIS - Astronomy Research using the Cornell Infra Red Imaging Spectrograph
ARCoIRIS is a cross-dispersed, single-object, longslit, infrared imaging spectrograph, containing no moving parts, and is based on an updated design of the three existing TripleSpec spectrographs installed on the 3.5m telescope at Apache Point Observatory, the 5m Hale telescope at Palomar Observatory, and on the 10m KECK2 telescope on Maunakea. ARCloIRIS features a fixed slit assembly of 1.1-arcsecs by 28-arcsecs. Spectra cover a simultaneous wavelength range of 0.80 to 2.47 misrons, at a spectral resolution of approx. 3500, encompassing the entire z'YJHK photometric range.
