The optical design of an integral field spectrometer for far-infrared observations, the Far-Infrared Field-Imaging Line Spectrometer (FIFI LS), is presented. The instrument will fly on board the joint NASA/DLR airborne observatory SOFIA, observing in two nearly independent wavelength channels simultaneously: a blue channel (40-105 lm) and a red channel (105-210 lm). To achieve instantaneous integral field spectroscopy for the first time in the far-infrared, a novel reflective image slicerdoi:10.1086/378225 fatcat:ht7yy2xjpjgrpaqy2wxfgkndjm
