ABSTRACT:
The invention relates to a refractometer and to a refractive index measuring method. The invention directs an incident light ray onto an interface of a medium of known refractive index and of the medium studied, then measuring the intensity of the reflected light ray. The ratio between the intensity of the incident ray and the intensity of the reflected ray allows the refractive index of the medium studied to be calculated by means of Fresnel's formulas.
