Optical Density - Learn Meaning, Definition, Formula and Units

WebOptical density may also mean the absolute value of the logarithm with base 10 of the power transmission factor of an optical attenuator: For example, an optical density of 3 means that the optical power is attenuated by the factor $10^3$ That would correspond to an attenuation by 30 decibels. If several attenuators are used in series, their ... WebThe optical density, or absorbance, of a material is a logarithmic ratio of light intensity entering versus exiting a particular material. The change in intensity is due to the tendency of atoms to dissipate some of the energy through vibration as light passes through it. ...
