WebNov 9, 2010 · The reflectance of a particular object or instance of material refers to the ratio of the total amount of light or electromagnetic radiation that is reflected from it’s surface compared to the total amount originally incident upon it. Reflectance is also sometimes referred to as a material’s reflection coefficient or reflection factor. WebIt also determines the separation of wavelengths known as chromatic aberration. Quantitatively, dispersion is inversely given by the Abbe number (vd) ( v d), which is a function of the refractive index of a material at the f (486.1nm), d (587.6nm), and c (656.3nm) wavelengths (Equation 1).
