Opacity vs density

WebOptical density, sometimes called extinction ( D ), is a useful parameter which can be calculated from opacity measurements: Optical density figures are small values which accurately describe transmittance and opacity. For example, an optical density of 1.0 indicates an opacity of approximately 90% and transmittance of about 10%. WebOptical density uses the same units as the quantity absorbance, and is expressed as the negative log of the transmission. It should be noted that one should not try to infer optical density from a transmission plot, a …
