WebJan 15, 2024 · Refractive index is one of the important properties and parameters of optical films (such as antireflective coatings, high reflectivity coatings, polarizing films, long/short wave filters, etc.). The main method for determining the optical constant of an optical film of MOFs is an ellipsometry method. WebThe refractive index n of a medium (e.g., water, olive oil, etc.), also called the index of refraction, is defined as the quotient of the speed of light in vacuum c and the speed of light in the medium v. It is a dimensionless number that depends on the temperature of the medium and the wavelength of the light beam.
