FIG. 1.

(Color online) Ellipsometer modified to allow HLGM measurements. Inset shows the azimuth and tilt angles describing the LC orientation.

(Color online) Experimental and simulated HLGM spectra (TM mode) for 5CB sample at (a) and (b).

Image of FIG. 3.
FIG. 3.

(Color online) Ordinary index dispersion for E7 and 5CB from different techniques and literature. Results for E7 are obtained at reduced temperature , the ones for 5CB correspond to the following reduced temperatures: in this paper, in Refs. 18 and 19, and in Ref. 8.

Image of FIG. 4.
FIG. 4.

(Color online) Extraordinary refractive index dispersion for E7 and 5CB. The temperatures are the same as in Fig. 3. The curves obtained by the ellipsometry fit are practically indistinguishable from those by HLGM fit.
