The CERGA stellar IR interferometer operates at a wavelength of 11 microns via a heterodyne system. The local oscillator is a CO2 laser tuned to the P56 line. The attained performance is short of theoretical predictions but present modifications promise a flux limit sufficient to permit the observation of more than 100 sources with a spatial resolution of 0.07 arc sec.
