Abstract

Fourier transform spectroscopy (FTS) combines the advantages of high resolution (sufficient to resolve Doppler line widths) with large optical throughput and an accurately linear wavenumber scale. The resolving power of about a million required for studies of atoms or molecules at 300 K has previously been achieved with the Imperial College FT spectrometer for VUV wavelengths down to 178 nm, the cut-off of the silica beamsplitter. This beamsplitter has a unique configuration, designed to ensure alignment at short wavelengths. We have now extended the wavelength range further into the VUV by replacing it with a similar beamsplitter made from a single MgF₂ crystal. The performance of the spectrometer with the new beamsplitter has been evaluated, and emission spectra from hollow cathode lamps have been recorded down to about 150 nm with a resolution of 0.08 cm^-1, representing a resolving power of 850,000.
