Abstract
A calorimetric method for continuous measurements of the optical absorption of bulk glasses over the spectrum extending from the visible to the near-infrared wavelength ranges is presented. A relation between the absorption and the induced temperature rise of the sample, at thermal equilibrium, is derived. Details for the most convenient arrangement of source, lens and monochromator are given. As an example, experimental results are plotted for a F2 glass.
