Two-modulator generalized ellipsometry is applied to determination of the optical functions of uniaxial rutile. For a nondepolarizing sample the two-modulator generalized ellipsometer determines all the elements of the normalized Jones matrix with one measurement and thereby totally characterizes light reflecting from the sample. If a uniaxial crystal is appropriately aligned, then determining its optical functions requires only a single measurement. We have used this new instrument to obtain optical functions of rutile that are the most accurate available for optical energies above the band edge.
