What Does ODU Stand For?
ODU stands for Optical Density Units
Optical Density Units (ODU) are a measurement of the opacity of a material or the attenuation of light. It quantifies the ability of a substance to absorb or transmit light, providing a logarithmic scale to evaluate changes in intensity. Used in various fields, including optics, photography, and scientific research, ODU helps in assessing filter efficiency, analyzing data from spectrophotometry, and designing optical systems.
