WebThe refractive index of a substance is dependent on the wavelength λ of the light and the temperature T of the substance. Reference to the refractive index must therefore also specify the wavelength and temperature, if the measurement is not done under standard conditions. The standard wavelength for refractometric measurements is 589 nm. WebAug 8, 2024 · References A. E. Kaifer, “Fundamentals of Analytical Chemistry.

WebThe refractive index depends on the wavelength of the incident beam, and the most accurate RI measurements are done with monochromatic light (usually 589 nm, the sodium D line). With optical corrections, white light can still be used for the measurements. WebThere are three main components in the refractometer; a light source, a prism, and an image detector. The light source sends light rays in different angles to the prism and process interface. Rays with a steep angle are partly reflected to the image detector and partly refracted to the process. johnny sweet and off the chartz
