We are nearing completion of the Infrared Multi-Object spectrometer (IRMOS), a joint effort of the STScI, GSFC, and KPNO. IRMOS achieves simultaneous observations of up to ~100 sources using a novel adjustable slit mask based on a Texas Instruments Digital Micromirror Device. This MEMS device provides a 848 x 600 element optical switch to select regions on the sky for spectroscopic observation. IRMOS is equipped with a 1024 x 1024 Rockwell Scientific HgCdTe Hawaii-1 detector array and gratings for R~300, 1000, and 3000 spectroscopy in the JHK bands (plus R~1000 in Z band). The IRMOS instrument has been assembled and is now in its final testing phase prior to delivery to KPNO in early 2004. We will discuss the current status and the measured performance of IRMOS.
