Optical density definition class 8
WebDefinition. Optical density, which ExxonMobil measures with a transmission densitometer, is another representation of a material's light-blocking ability. The optical density scale is unitless and logarithmic, and it enhances the data resolution for materials that transmit only a small fraction of incident light. ExxonMobil uses optical density ...

For example, a “50% neutral density filter” would cut the intensity of transmitted light in half, without favoring one color over another and without making any brighter or dimmer patches. A neutral density filter would make a good lens for untinted sunglasses. – rob ♦
WebOptical density (OD) measurement of bacterial cultures is a common technique used in microbiology. Researchers have primarily relied on spectrophotometers to make these measurements, however the measurement is actually based on the amount of light scattered by the culture rather than the amount of light absorbed. WebOptical density is a mathematical way of describing the extent of attenuation of visual lightwaves. Density is the log of opacity. Opacity is the reciprocal of transmittance. So a …
