WebOptical density is a mathematical way of describing the extent of attenuation of visual lightwaves. Density is the log of opacity. Opacity is the reciprocal of transmittance. So a … WebIt is used to determine whether power is isolated within a specific frequency range, called a frequency peak, or if the data are a form of noise. It is called a density because it is a measure of the power per unit frequency, so kind of like a linear mass density with units of mass per unit length (very loose analogy here).

Radiant flux - Wikipedia

WebIn radiometry, radiant flux or radiant power is the radiant energy emitted, reflected, transmitted, or received per unit time, and spectral flux or spectral power is the radiant flux per unit frequency or wavelength, depending on whether the spectrum is taken as a function of frequency or of wavelength. The SI unit of radiant flux is the watt (W), one joule per … WebOptical Density (OD) describes the amount of energy blocked or rejected by a filter. A high optical density value indicates low transmission, and low optical density indicates high transmission.
