<p>We have used seven different techniques to measure the anisotropic refractive index of poly(vinylcarbazole) films. These techniques are: two types of variable angle spectroscopic ellipsometry (VASE) with multiple sample analysis, Interference enhanced VASE, Transmittance combined with VASE, Polarised Reflectance, beta-scan VASE, and prism coupling. We have found the average ordinary and extraordinary indices at 633 nm to be <em>n<sub>o</sub></em> = <em>n<sub>TE</sub></em> = 1.675 ± 0.008, and <em>n<sub>e</sub></em> = <em>n<sub>TM</sub></em> = 1.722 ± 0.018, respectively, consistent amongst methods and conclusive on the magnitude of Δ<em>n</em> in polymer films.</p>
