A grating spectrometer with medium spectral resolution was developed for the GIRL project (Experiment E3), for the determination of the emission of trace constituents in the Earth's atmosphere, and for planetary and astronomical measurements. The spectrometer consists of two Ebert-Fastie spectrometers covering the wavelength range between 2.5 and 100 micron. The engineering model of E3 is described, and the design data are given. The engineering model was verified during operation in a cryostat at liquid helium temperatures. The spectral channels and respective IR filters were designed. Stray light suppression during limb scan measurements is explained. Absorption and emission spectra of atmospheric trace gases were measured.
