WebOptical density equals the log to the base 10 of the reciprocal of the transmittance. where t l is transmittance. In spectroscopy, optical density is the measure of absorbance, and is defined as the ratio of the intensity of light falling upon a material and the intensity transmitted. Abbreviation OD. Products & Suppliers 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.
WebOptical Density. This value indicates light transmittance and is used for white and black type films. The higher the optical density, the lower the transmittance. When the transmittance is 100%, the optical density is 0. Measured using an optical densitometer.
