We present preliminary results on a program aimed at characterizing the optical properties of materials of potential usage in filters for soft x-ray detectors. In particular, we discuss a method that we have used to derive and model the refractive index n and the extinction coefficient k of thin plastic film materials. The method is based on best fit estimates of the parameters of a quanto- mechanical model describing k. The value of n is then evaluated using the Kramers-Kronig relationship… CONTINUE READING
