WebThe birefringence of a fibre is often determined by measuring the two principal refractive indices and subtracting one from the other. It can also be measured directly, however, by determining the retardation, or difference in optical path length, of the one principal ray relative to the other. WebWhat does birefringence mean?

Webbirefringence, i.e., optical retardation per unit of thickness (typically, nm/cm). In addition, an accurate observation of color shifts requires a precise orientation of the sample between the polarizers. This technique is generally subjective, and relies heavily on the trained observation skills of the individual operator. It also relies on the WebApr 7, 2024 · Birefringence = Retardation / thickness nm (multiply width in microns x 1000 to convert to nm) = 975nm/ 80 µm x 1000 to convert to nm. = 0.012.
