An overview of the instrumentation developed for the quality control of the optical properties of fluid components of RICH detectors is presented. An on-line data acquisition and control system for operation of a refractometer in the UV and VUV region is presented. The possibility of simultaneous measurement of transmittance and refractivity using a Fabry-Perot refractometer in the UV and VUV region is discussed. The accuracy of the refractometer in the n - 1 determination of atmospheric air is presently 0.3% at 255 nm and about 1% at 185 nm. It is expected to improve when measuring the refractivities of the fluorocarbons used as radiators in RICH detectors. (EN)
