Paper Abstract

The experimental model of laser interference refractometer and thicknessmeter (IRT) for simultaneous measurement of absolute refractive index and thickness of the plane parallel samples has been developed, manufactured and investigated. This IRT allows to test solid, liquid and gaseous media, including optical crystals, plastics and other sheet materials, over a wide spectral range. IRT accuracy of refractive index measurement is not worse than from the best modern goniometers and accuracy of thickness measurement corresponds to the interference accuracy.
