Abstract: An illuminator for use in a refractometer having a body housing, a sample cover assembly, a prism assembly and measuring assembly for measuring the composition and density of a substance. The illuminator includes a light source, a power source for operating the light source and an operating means for selectively activating the light source. The illuminator is located in the refractometer housing such that the light source is in a position on or about the prism assembly to illuminate a fluid substance to be measured. Light from the light source is introduced at a grazing incidence to a measuring surface of the prism. Phosphorescent material in the sample cover provides reticle illumination.
