IFI LS是德国索菲亚航空天文台的远红外积分场光谱仪。该仪器由两个独立的积分场光谱仪组成，用于两个不同的波段（45-110 μm和100-200 μm）。二向色滤光片可以在同一视场中同时观察两条不同的光谱线。这允许在许多重要的远红外冷却线中使用FIFLS非常有效地映射扩展区域，其中线比率对温度和密度敏感。IFI LS将成为索菲亚的设施工具。在未来两年内，它将成为一个完全调试的设施仪器。在投入使用后，IFI LS将可用于具有巨大科学潜力的一般观测。在本文中，我们还将讨论科学的FIFI LS。
FIFI LS is the German far-infrared integral field spectrometer for the SOFIA airborne observatory. The instrument consists of two independent integral field spectrometers for two different wavelength bands (45-110 μm and 100-200 μm). A dichroic filter enables simultaneous observation of two different spectral lines in the same field-of view. This allows very efficient mapping of extended regions with FIFI LS in many important far-infrared cooling lines with line ratios sensitive to temperature and density. FIFI LS will become a facility instrument for SOFIA. In the next two years it will become a fully commissioned facility instrument. After its commission, FIFI LS will be available for general observing with a large science potential. In this paper, we will also discuss the science of FIFI LS.
