The index of a glass can be altered over a range of up to 1×10-4 (that is, 1 in the fourth decimal place) by the changing of an annealing schedule.These refractive indices are called relative refractive indices, for short. Each type of glass has a different structure and therefore a different IOR value assigned to it.
used the resultant speckle to measure the refractive index with a resolution on the order of 10 –6. Traveling through all other … Many materials have a well-characterized refractive index, but these indexes often depend strongly upon the frequency of light, causing optical dispersion. J.3–2. For those few millimeters, the light slows down, just to accelerate again.
