    Abstract

    An infrared meander-line waveplate has been modeled and measured over the 8 to 12 mu m spectral band in terms of its differential phase delay, axial ratio of the output polarization ellipse, and power throughput for angles of incidence between 0 degrees and 60 degrees. The study has been performed for planes of incidence parallel and perpendicular to the meander-line axis. The main significance is that the phase delay remains almost unaffected by the angle of incidence. Infrared meander-line retarders can thus be used well beyond the paraxial range as in low-f/# optical systems and in non-normal-incidence applications. (c) 2007 Optical Society of America.
