Abstract

The design principles and the modes of operation of an interference refractometer, made up of standard components of a cube corner interferometer for length measurements, are presented. Equipped with a reference path of rays, the refractive index of air and the displacement of the cube corner reflector may be measured simultaneously. It has been shown, that this system is well suited for absolute measurements of the refractive index of air in high precision metrology.
