Absorbance - Wikipedia, the free encyclopedia In spectroscopy, the absorbance (also called optical density[2][3]) of a material is a logarithmic ratio of the amount of radiation falling upon a material to the amount of radiation transmitted through the material.[4][5] Absorbance measurements are ofte
Absorbance - Ocean Optics The most common way to measure the absorbance of a solution is in a standard 1 cm pathlength cuvette, whether it be a disposable plastic UV-VIS cuvette or a high-quality quartz cuvette. This is typically a good pathlength unless the sample happens to be v
