Definition noun (1) The measure of transmittance of an optical medium for a given wavelength. The higher the OD the lower the transmittance, the higher protection factor by a filter (e.g. goggles, viewing windows, etc.). (2) The measure of the amount of light absorbed by a suspension of bacterial cells or a solution of an..Read More

Keep your components separated with this 50-pack of 4mm-long (0.16") nylon spacers. These spacers have an outer diameter (OD) of 4 mm (0.16") and an inner diameter (ID) of 2.7 mm (0.11"), and they work with #2 and M2 screws.

In this tutorial, the works of Carl Gustav Jung and Sigmund Freud are described. Both of them actively pursued the way h..

Definition noun (1) The measure of transmittance of an optical medium for a given wavelength. The higher the OD the lower the transmittance, the higher protection factor by a filter (e.g. goggles, viewing windows, etc.). (2) The measure of the amount of light absorbed by a suspension of bacterial cells or a solution of an organic molecule with the use of a colourimeter or spectrophotometer. Supplement In microbiology, the values can be used to measure turbidity, which in turn is used to estimate the number of bacteria (or concentration of molecules like proteins) in a solution. Abbreviation: OD Synonym: absorbance. See also: absorption.
