摘要：

A liquid-He-cooled spectrometer is being developed as a facility instrument for the Kuiper Airborne Observatory (KAO), primarily to study far-infrared (FIR) lines originating in the interstellar medium. It achieves a maximum resolving power of approx. 6000 by means of a 45 cm long echelle grating and is optically capable of operating in the spectral range from 25 to 300 mu m. An array of detectors is used to measure simultaneously a line and the adjacent continuum from astronomical sources. Currently six detectors allow measuremnts in the 30-120 mu m spectral band. This summary briefly describes the instrument and its performance.
