WebJun 9, 2024 · Today, the standard refractive index, is typically expressed in the unit nD. nD is based on the sodium lamp, which generates a double wavelength light (588.995 nm and 589.592 nm). And we take the center of two wavelengths to determine the absolute refraction, that is, 589.3nm. WebRefractometry is the analytical method of measuring substances' refractive index (one of their fundamental physical properties) in order to, for example, assess their composition or purity. A refractometer is the instrument used to measure refractive index ("RI").
