ABSTRACT:
The present invention provides a method and apparatus for impressing a diffraction image into an oriented polymeric film wherein, after orientation of the film, the temperature of the film is raised to a desired annealing temperature, the film temperature being continuously maintained above room temperature while a diffraction pattern is embossed directly into the surface of the film.
