Index of refraction of germanium

Applied Optics, 2020
Measurements of the index of refraction of a sample of high-quality, single-crystal germanium using the minimum deviation refractometry method are presented for temperatures near 22°C and for wavelengths in the range 2 to 14 µm. The standard uncertainty for the measurements ranges from 1.5 × 10 −

The Index of Refraction

American Journal of Physics, 1972
The phase velocity c/n of waves in a dielectric medium is known to arise from the interference of incident waves and waves emitted by the atoms in the medium, all traveling with speed c. As a model of a dielectric we consider a number of parallel sheets of charge with an electromagnetic wave normally incident on the sheets.

Conversion of group refractive index to phase refractive index

Journal of the Optical Society of America A, 1988
The so-called group index of refraction may be measured by observing the shift of the visibility envelope when a sample is inserted into one arm of a Twyman–Green interferometer. Although the group and phase index curves are related, the phase index cannot be directly calculated from the group index because there are infinitely many phase index curves ...
