Abstract
This monochromator is made up of a number of discrete narrow band interference filters mounted on a drum which rotates with respect to a light beam so that as the light beam passes through each of the filter the angle of incidence of the light beam changes with respect to the filter. Each of the filters is for a different normal wavelength of peak transmission so that spectral analysis of the light source can be obtained.
