Abstract
In an optical system for measuring sample absorption of light at a primary wavelength output from a monochromator, a method of subtracting the effect of secondary wavelength components of light from the monochromator. The sample absorption of light at the primary wavelength including the effect of the secondary wavelength components and at the secondary wavelength are determined. The results are used to obtain the sample absorption of light at the primary wavelength without the effect of the secondary wavelength components.
