WebIn optics, vergence is the angle formed by rays of light that are not perfectly parallel to one another. Rays that move closer to the optical axis as they propagate are said to be converging, while rays that move away from the axis are diverging. WebMay 4, 2012 · Let me provide an operational definition of optical density: Write the number 1 and follow it with as many zeroes as the optical density. The number you get is the optical attenuation. Example: after passing a filter of optical density 6, the outgoing light has been attenuated one million times. Hope this is clear enough.
