Method and equipment for measuring absorption of light scattering materials.

摘要

In order to make it possible to measure the light absorption coefficient of various sorts of substances contained in a light scattering material (18) with a high precision, a method is disclosed, by which wavelength of light (15, 23, 28, 34) transmitted through the light scattering material (18) is varied and the coefficient of light absorption ( alpha ) is calculated, starting from a ratio of variations in the intensity of the transmitted light to variations in the wavelength. <IMAGE>
