Optical density formula. An optical density is defined as an equation given by, Optical density (O.D.) = log₁₀ Io / It. The optical density of any medium is defined as the logarithmic ratio of the intensity of incident light (Io) to the intensity of the transmitted light (It) passing through that medium.
