| Description | Journal: Journal of Physics E: Scientific Instruments A Fourier transform spectrometer designed to operate at high resolution at wavelengths down to 170 nm is described. The principal instrumental parameters are: mirror travel, 200 mm; resolving limit, 0.025 $cm^{-1}$; collimator aperture ratio, f/25; overall dimensions of vacuum tank, 1.5 m*0.25 m*0.25 m. Test results show (i) a signal-to-noise ratio in the transformed spectrum at 200 nm better than 1000:1 for an iron-neon hollow cathode lamp at a resolving power of quarter of a million, (ii) fully resolved line profiles in the same source at a resolving limit of 0.03 $cm^{-1}$ (resolving power $1.5*10^{6}$), (iii) relative wavenumbers of Fe II emission lines reproducible to +or-0.0006 $cm^{-1}$ (3.4 fm), and (iv) a significant luminosity gain over grating spectrometers operating in the same region. |
