Paper Abstract

THe experimental model of laser interferometer for measurement of absolute refractive index and thickness of optical media had been created and investigated. The interferometer allows to test both solid, liquid and gaseous media. The sample for measurement should be in a form of a plane parallel plate. The interferometer permits to measure the geometrical thickness of the plane parallel samples with interference accuracy, simultaneously with the refractive index measurement. The mathematical simulation of measuring process with PC has ben performed. The results of investigations of the interferometer precision possibilities are presented.
