Abstract

An optical interference method for simultaneous determination of the temperature dependences of refractive index n(T) and thickness 1(T) of transparent parallel-plane samples has been worked out. The method has been applied to a glass plate sample, and it was shown that dn/dT and (d1/dT)/1) temperature derivatives satisfactorily correlate with corresponding reference data. The determined inaccuracies of temperature changes of (delta) n/n and (delta) 1/1 have not exceeded 10^-4. Investigation of (NH₄)₂SbF₅ crystal by the proposed optical-interference method has confirmed the occurrence of the second order phase transitions at 292 and 168 K.
