Handheld refractometers and Abbe refractometers use transmitted light: The light beam goes through two right-angled prisms, an illumination prism and a measurement prism. Both prisms are made from glass with the same refractive index and are pressed against each other. The sample is placed in the space between these two prisms.Most refractometers instead make use of the critical angle effect. When light passes from a more dense to a less dense medium, it may be refracted, as shown in Figure 28.18(b), but if the angle i 2 becomes so large that the ray cannot emerge from the dense medium, the ray is totally internally reflected, as illustrated in Figure 28.18(c). A refractometer measures the index of refraction for a material, which could be a gas, a liquid or a transparent solid such as glass. They achieve this by passing light through the sample and measuring the refraction — the amount that the light bends. Most commonly, aqueous solutions are measured, providing an indication concentration. Examples.
