Abstract
The performance of a refractometer for operation in the DELPHI Ring Im aging Cherenkov detectors for operation in the far UV region is presen ted. Comparisons are made with performance in standard laboratory cond itions. Data on absolute refractivities are given for reference sample s of air, argon, Freon 12 as well as on gaseous C4F10 from the Forward RICH detector of DELPHI. The accuracy of the determination of the n-1 using this refractometer at the 253.7 nm is estimated about 1% for C4 F10.
