Abstract
In the present work , effect of addition Lithium Fluoride on some optical properties of poly-methyl methacrylate has been studied . for that purpose , many samples has been prepared by adding Lithium Fluoride on the poly-methyl methacrylate by different weight percentages from these salts with polymer and by different thickness .The absorption and transmission spectra has been recorded in the wavelength range (300-1100)nm . The absorption coefficient and energy gap of the indirect, allowed, forbidden transition have been determined.
