device for measuring the refractive index of fluessigkeiten or gases, particularly for determining the mischungsverhaeltnisses several components such fluessigkeiten or gases
The light conductor apparatus is for measuring the refractive index of fluids and determining the mixture-ratios of the fluid components and the fluid temperature. An end-face window of a light conductor has both a radiation source and a photosensitive member coupled to it. A portion of the light conductor's surface has a surface-of-rotation which has a progressively decreasing radius of curvature extending toward a vertex-tip, measuring, surface area. Light which is reflected from the vertex-tip, measuring, surface area to the photosensitive member provides an indication of an unknown refractive index of a fluid adjacent to the vertex-tip, surface area.
