The Michigan Infrared Beam Combiner (MIRC) combines the light from all six CHARA telescopes simultaneously.  It disperses light across 8 spectral channels in the near infrared H-band (1.6 microns).  It was developed by John Monnier and his optical interferometry group in the Astronomy Department at the University of Michigan.  MIRC has produced the first images of a main sequence star other than the sun and has measured starpots on the surface of magnetically active stars.
