The ellipsometer system consists of four vacuum chambers accommodating a continuum light source of a laser produced plasma driven by a Q-switched Nd:YAG laser, a concave focusing mirror, a constant-deviation angle monochromator, and a reflectometer chamber in which newly polarizing elements are installed. With the ellipsometer, a multilayer transmission phase shifter was evaluated by transmission ellipsometry. The amplitude transmittance Tp/Ts between p- and s- components were found, where the retardation angle of 80.7° is large enough for various polarimetry measurements. With the multilayer polarizers and the phase shifter, normalized Stokes parameters of the beam from the monochromator was measured, which showed that the beam is mostly unpolarized.
