Optical Performance of Doped Azopolyester and its Application

摘要: Theoretical and experimental investigations on the optical behavior of thin films mainly deal with band gap, reflection, transmission, absorption their relation to constants. The transmittance spectra are recorded from 100 1000nm wavelength using a Hitachi UV-VIS-NIR spectrophotometer (Model-JASCO V-570) doped Azopolyester were observed. Unpolarized radiation at room temperature resolution 2nm was used in this study. measurements made typical uniform thickness 5μm deposited glass substrate. substrate corrected by introducing an uncoated cleaned reference beam. study / is useful method for investigation optically induced transitions which provide information structure energy gap both crystalline non-crystalline materials. Finally applications fiber optic cable telecommunication discussed.
