1/2 Polymers 04 Raman Imaging of Holographic Gratings Inscribed on Polymer Thin Films. F.Lagugné-Labarthet and David Talaga LPCM, UMR 5803 CNRS, Université Bordeaux 1, 351, Cours de la Libération, 33405 Talence cedex, France Raman image (Figure 1) from a thin film of azobenzene-containing polymer thin film (300 nm) that is periodically structured (periodicity of ~1 µm). Raman measurements were recorded with a Labram HR 800 (HORIBA JobinYvon) spectrometer combined with an inverted microscope (Olympus IX 71) and a X,Y Piezoelectric stage to position the sample with the best accuracy and repeatability. A 100X, 0.9 NA microscope objective was used. A Raman spectrum (Fig. 2) was recorded every 100 nm along the X and Y directions with an integration time of 5 secon
