Measuring Transparency

Refractive Index (ISO 489 / ASTM D542)

The refractive index, or index of refraction, is the ratio of the velocity of light in a vacuum to its velocity in the material in question. The refractive index is useful in identifying materials and is an important performance indicator in optical application.

The Index of refraction can be calculated using Snell's Law:

n1 / n2 = sin Ɵ2 / Ɵ1

where n1 and n2 are the refractive indices of mediums 1 and 2, Ɵ1 is the angle of incidence and Ɵ2 is the angle of refraction.
