The cryogenically cooled IR camera designated IRCAM uses a 62 x 58-element InSb array capable of reading noises of about 450 electrons rms, and dark currents of about 100 electrons/sec. IRCAM, which is typically operated at about 35 K, achieves background-limited performance throughout the 1-5 micron region. Despite certain limitations, flat-fielding accuracies have been demonstrated to better than 1 part in 10,000, and relative photometry to better than about 0.01 mag, or 1 percent. Recent results are presented from star-forming regions, galaxies, the Galactic center, planetary nebulae, SNRs, and deep cosmological surveys.
