Figures (3)

Fig. 1
Fig. 1

Negative image of the film in crossed polarizers. The dark strips correspond to anisotropic regions.

Fig. 2
Fig. 2

Spectral transmittance curves for seven anisotropic regions of the film in crossed polarizers. The vertical axis represents the intensity of the light given in relative units. The horizontal axis represents the wavelength in nanometers. The curves are innumerated according to decreasing brightness in the seven anisotropic regions. Curve 8 is straight because of weak anisotropy, and curve 9 is very much like curve 1. Thus these curves are omitted.

Fig. 3
Fig. 3

Image of part of the film at 200 triple magnification. The dark part corresponds to the anisotropic region of the film and the light one to the isotropic region.
