A simple refractive index cell for use in the spectral range between 0.2-20 mm<sup>-1</sup> is described. The module is designed to be compatible with a Beckman-FS720 interferometer and it is extremely easy to align and use. The cell has the advantage of high energy throughput and low reflection losses from the thin polymer front window. The results obtained for liquid tetrabromoethane and p-difluorobenzene agree within 1-2% of the published data, the random error in our measurements being about +or-1%.
