Paper Abstract

Using index matched polymer lightguides the optical anisotropy of planar polymer films is measured with an accuracy (Delta) (Nu) <EQ 10-5. The investigation is performed with heated guides in the range of 40 degree(s)C to 110 degree(s)C. An anomaly of (Delta) (Nu) (T) at the glass transition is found. This method may be used for the determination of the glass transition of films in the thickness range of optical lightguides.
