WebDec 30, 2024 · In the optically thin regime, the amount of extinction (absorption plus scattering) is simply related to the amount of material: double the amount of stuff, double the extinction. There is hope, then, that if we can measure the amount of light absorbed (or emitted) by the gas, we can calculate exactly how much gas there is. optically thick: τ > > 1 WebOD600. OD600 (Also written as O.D. 600, D600, o.d. 600, OD600) is an abbreviation indicating the optical density of a sample measured at a wavelength of 600 nm. It is a commonly used in Spectrophotometry for estimating the concentration of bacteria or other cells in a liquid as the 600nm wavelength does little to damage or hinder their growth.
