How does a refractometer work?

Refractometers are instruments used in measuring the index of refraction in liquid, gas and translucent solids. They usually have a prism screen and eye piece with a Brix scale, 2-3 drops of a solution to be measured are added to the prism, the refractometer is then pointed in the direction of a light source. The prism possesses a greater refractive index than the sample solution to be measured. In a weak sample the difference between the refractive index of the solution and the prism is great, therefore the angle of refraction is large on the scale. In a strong sample the opposite is shown, so a smaller angle of refraction on the scale. The prism and sample must both be at the same temperature to ensure accurate results.
